    Accurate, Scalable Speech-to-Text with Powerful AI Features and Easy Integration

    Reviewed on Jul 31, 2026
    Review provided by G2
    What do you like best about the product?
    AssemblyAI delivers highly accurate speech-to-text transcription through a simple, well-documented API that is easy to integrate into production applications. Beyond transcription, features such as speaker diarization, summarization, sentiment analysis, content moderation, and entity detection provide significant value without requiring additional AI services. The API is reliable, scales well under production workloads, and offers fast processing times, while the documentation and SDKs make onboarding straightforward. Overall, it reduces development effort and delivers strong ROI for voice-enabled applications.
    What do you dislike about the product?
    Although AssemblyAI is easy to integrate, processing costs can become significant for applications with high audio volumes. Some advanced AI models also introduce longer processing times compared to basic transcription. I'd like to see more native integrations with third-party platforms, additional customization for speech models, and more granular controls over AI features. While documentation is comprehensive, a larger collection of production-ready implementation examples would further simplify complex use cases.
    What problems is the product solving and how is that benefiting you?
    Before using AssemblyAI, extracting insights from audio recordings required manual transcription or multiple specialized tools. AssemblyAI consolidated transcription, speech analysis, summarization, and content intelligence into a single API, significantly reducing development complexity. This has shortened implementation time, automated previously manual workflows, improved the accessibility and searchability of audio content, and enabled faster delivery of AI-powered features while reducing operational costs and increasing overall productivity.

    Reliable, Easy-to-Use Platform That Streamlines Our Workflow

    Reviewed on Jul 28, 2026
    Review provided by G2
    What do you like best about the product?
    AssemblyAI has been a reliable solution that helped streamline our workflow. The interface is easy to navigate, performance has been consistent, and the documentation and overall experience make it simple to get value quickly. I appreciate the regular improvements and would recommend it to teams looking for a dependable platform in its category.
    What do you dislike about the product?
    While I've had a positive experience overall, I've noticed that pricing can become expensive as usage scales. I've also seen occasional accuracy issues with noisy audio or multiple speakers, and there are some limitations when it comes to customization and certain real-time use cases.
    What problems is the product solving and how is that benefiting you?
    AssemblyAI has simplified our transcription workflow by providing fast, accurate speech-to-text and AI-powered audio insights through an easy-to-use API. It has reduced manual effort, sped up development, and allowed us to focus more on building our product rather than managing transcription infrastructure.

    Reviewed on Jul 28, 2026
    Review provided by G2
    What do you like best about the product?
    The real-time live translation feature made the app I built come alive. It added an immediate, dynamic feel that really improved the overall experience.
    What do you dislike about the product?
    The documentation didn’t include many sample apps to guide me through, so I had to figure a lot of things out on my own.
    What problems is the product solving and how is that benefiting you?
    This is a transcription API for documents and speech-to-text, and I use it for conversations.

    Highly Accurate Transcriptions with Flexible Audio Processing Options

    Reviewed on Jul 28, 2026
    Review provided by G2
    What do you like best about the product?
    What I like best about the software is its transcription accuracy and the multiple options available to me when processing my audio.
    What do you dislike about the product?
    The only thing I disliked about my experience: while on the free plan with provided credits to test out the platform, I was unaware that submitted content was being used to train their system. The ability to opt out is only once you've moved to a paid plan.
    What problems is the product solving and how is that benefiting you?
    I like how they've set up their UI for their playground. It allows you to quickly test different scenarios before you implement them in your integrations, which we have done in n8n.

    It has performed better than other AI transcription tools, as far as accuracy, but also in feature set, like being able to export word-level timestamps in JSON format.

    So getting set up and going with the app has been frictionless.

    Fast, Accurate Transcription with Clear Docs and Powerful Built-In Features

    Reviewed on Jul 27, 2026
    Review provided by G2
    What do you like best about the product?
    AssemblyAI is easy to use and delivers fast, accurate speech-to-text transcription. The API documentation is clear and thorough, making it straightforward to integrate smoothly into applications. I also appreciate the useful built-in features, such as speaker identification, summarisation, and sentiment analysis.
    What do you dislike about the product?
    Transcription accuracy can occasionally drop when the audio includes strong accents or a lot of background noise. Processing larger files may also take longer, and the pricing can become expensive if you need high-volume usage.
    What problems is the product solving and how is that benefiting you?
    AssemblyAI automates speech-to-text transcription and audio analysis, removing the need for manual transcription. This saves time and boosts productivity, while also making it easier to search, summarise, and analyse audio content from meetings, interviews, and customer conversations.

    AssemblyAI Makes Transcription Fast with Clear, Easy-to-Use API Docs

    Reviewed on Jul 21, 2026
    Review provided by G2
    What do you like best about the product?
    I started using AssemblyAI when I needed a quick way to convert recorded audio into text for notes and content planning. The API documentation is easy to follow, and testing the transcription service didn't take much time. The transcripts were clear enough for me to review and edit instead of typing everything manually, which made the whole process faster.
    What do you dislike about the product?
    For most recordings the results are good, but audio with background noise or multiple speakers sometimes needs a quick manual review. The free credits are useful for testing, although they can be used up fairly quickly if you're processing several files.
    What problems is the product solving and how is that benefiting you?
    AssemblyAI helps me turn audio into searchable text without spending time typing everything myself. I use it when I need to extract information from recordings or prepare written notes. It speeds up the workflow, makes important points easier to find later, and saves time compared to manual transcription.

    Accurate transcripts and fast translations have reduced my interview processing time

    Reviewed on Jul 15, 2026
    Review provided by PeerSpot

    What is our primary use case?

    The main use case of AssemblyAI is for transcription purposes. Whenever I work on a file, specifically when I moderate or take an interview, I need to have a transcript. I mostly use AssemblyAI to make my proper transcript.

    I did have some projects recently that required me to do some transcription work. That was the time when I used AssemblyAI to make my work easier. What I appreciate about AssemblyAI is that it gives me an error-free transcript file. That is why I used it in a few of the multiple projects that I have done in the past few months.

    I mostly use AssemblyAI on my personal projects. I do not know if the whole organization is using it or not. On my personal preference for my projects, whenever I require some kind of transcript, I personally use AssemblyAI. It is my first go-to for any transcript, any transcription purposes, any conversion, or any language change purposes.

    What is most valuable?

    I think the best feature AssemblyAI offers for me is the errorless transcription and language translation. If I have a file or a whole transcript of any session in any other language, it translates it for me. Whatever I needed. That is something I really love about AssemblyAI.

    Speed and accuracy both matter to me.

    What needs improvement?

    The only point where I think AssemblyAI can be improved is in the export functionality. For example, if I copy the whole text from the AssemblyAI dashboard and paste it into a Word file, it generally takes a single type of format that is very misaligned. With my experience, I first copy the whole text from the moderator, transcriber, and respondent into a Notepad. Then, after the Notepad, I copy it into a Word file, and then it works completely fine with no alignment error. AssemblyAI can work on this. On a better scale, I could directly take it or directly share the transcript into a Word file in a proper format and edit it accordingly. That would be helpful.

    The only thing I miss is that I am unable to get it in a proper file in just one click. I just need something where with one click it should be in my Word file, all in order and everything. That is the point I am missing, and I think AssemblyAI can address that.

    For how long have I used the solution?

    I have been using AssemblyAI for two years.

    What do I think about the stability of the solution?

    AssemblyAI is completely stable.

    What do I think about the scalability of the solution?

    I do not think there are any scalability issues. I actually love using AssemblyAI.

    How are customer service and support?

    I have never had a chance to ask for customer support. AssemblyAI has never created any problem for me.

    Which solution did I use previously and why did I switch?

    Before, I was using Temi, which is also a transcription website that makes transcripts. I switched to AssemblyAI because, in comparison to Temi, AssemblyAI is faster, more accurate, and it automatically removes all the unfiltered words that Temi generally does not remove. With Temi, once I have a transcript, I have to work more, around two or three hours, to do a quality check of the transcript. But with AssemblyAI, I do not need to do much quality check. I can do it within an hour. That is the point when I switched to AssemblyAI, and I really appreciated that.

    How was the initial setup?

    I would say that they should definitely try this. AssemblyAI can make work really easier and faster. Why would I wish to spend more than four to five hours on a single one-hour transcript if with AssemblyAI I can do it within forty minutes?

    What was our ROI?

    Due to its user-friendliness, its errorless transcriptions, and the fact that I can use it anywhere, anytime.

    What's my experience with pricing, setup cost, and licensing?

    I do not have a subscription for AssemblyAI for now. I only used it on a trial basis. But I really love its platform. So most probably, in the future, I am going to get a subscription to AssemblyAI.

    Which other solutions did I evaluate?

    I did not evaluate any other options. I was pretty clear that I wanted to use AssemblyAI.

    What other advice do I have?

    For my personal project, I remember there was a project around eight months ago where I was doing work that required some transcription, and the transcripts were originally in German and Japanese, and I needed to deliver some of the transcript in English. At that time, I used AssemblyAI to moderate my work, and it actually helped me to cut down the time that it generally takes me to deliver a specific transcript that is translated, errorless, and in a proper format. AssemblyAI helped me a lot in that situation. I would rate this experience a 9 out of 10.

    Easy Setup, Clear Docs, and Fast, High-Quality Transcription

    Reviewed on Jul 11, 2026
    Review provided by G2
    What do you like best about the product?
    What I like most about AssemblyAI is how easy it is to get started. The API documentation is clear, and the dashboard is simple to navigate. I was able to test speech-to-text features without spending much time on setup. The transcription quality was good, and the processing speed was impressive for the audio files I tested.
    What do you dislike about the product?
    The free credits are helpful for getting started, but they run out fairly quickly if you're testing multiple audio files. I also think it would be nice if the dashboard provided a few more examples for beginners. Other than that, I had a smooth experience using the platform.
    What problems is the product solving and how is that benefiting you?
    AssemblyAI makes it easy to convert audio into text without having to build a speech recognition solution from scratch. It saved me time when testing transcription features, and having everything managed through a simple dashboard and API made the process much more convenient.

    Natural voice calls have transformed how our customers converse with automated agents

    Reviewed on Jul 09, 2026
    Review from a verified AWS customer

    What is our primary use case?

    My main use case for AssemblyAI was for a voice-based calling system that we created.

    A specific example of how I used AssemblyAI in my voice-based calling system is that it was used for the text-to-speech part and also speech-to-text. For speech-to-text, I don't remember if we also used something else, but for text-to-speech, we definitely relied on AssemblyAI because the voices were significantly better.

    I don't have anything else to add about my use case with AssemblyAI.

    What is most valuable?

    The best features AssemblyAI offers include a large selection of voices and an intuitive dashboard where we could customize and tweak things according to what we needed.

    When I mention customizing and tweaking things, it was a mix of all aspects, and I could also change the AI model behind it.

    AssemblyAI has impacted my organization positively, not in the current organization, but in the previous organization. Because of AssemblyAI, we were able to envision something that could speak naturally to mass consumers.

    That natural-sounding speech impacted our customers because users couldn't tell if it was AI, and even if they could, they could still have a natural conversation.

    What needs improvement?

    AssemblyAI can be improved in several areas. I don't remember if AssemblyAI had a webhook, but if they have one, that's beneficial. The biggest improvement I think was the lack of background sound. If AssemblyAI doesn't have this feature anymore, but suppose we have a use case where a customer support representative is talking to an actual customer, for it to actually sound natural, perhaps a dim office workspace background would be nice. This would give it a much more natural feel instead of a very silent background, which feels very artificial.

    Regarding AssemblyAI's AI capabilities, I have no idea about its governance and security. I would really like to know if it is compliant with Saudi PDPL. A feature I would want AssemblyAI to have is to cater to the MENA region and the Middle East market. There's a law in Saudi called PDPL, Personal Data Privacy Law, and that dictates that all the data should remain within the Kingdom or within GCC and all the processing should happen there. If AssemblyAI could offer some feature or some way to ensure that the hosting is being done within maybe GCP Dammam or AWS in the GCC, or the cloud providers that reside here, and the physical data centers that are being used are of the GCC for our entire processing, that would make it so much more feasible to be used within organizations in Saudi.

    Regarding AssemblyAI's AI capabilities, I can't think much about its accuracy and reliability of output because I think the AI is of a third party that is connected. I don't know if AssemblyAI has any LLM that does the reasoning. So I don't think it's fair to say it's AssemblyAI's capability.

    For how long have I used the solution?

    I used AssemblyAI for one and a half years, but I haven't been using it for a year now.

    What other advice do I have?

    I would say to others looking into using AssemblyAI that it's a good start and it's very easy. They should start by first using the dashboard and trying it out instead of jumping into integrations to see if it best fits their use case. I would rate my overall experience with AssemblyAI an 8 out of 10.
