Fast, Reliable Voice Stack with Low Latency and Easy API Integration
Reviewed on Apr 22, 2026
Review provided by G2
What do you like best about the product?
What I like best about smallest.ai is how fast and reliable the voice stack feels compared to most alternatives I’ve tried. The latency is noticeably low, which makes a big difference when you’re building real-time or near real-time experiences. The APIs are also very straightforward to integrate, so you can go from idea to a working prototype pretty quickly without a lot of overhead.
What do you dislike about the product?
There are times when I want more control or transparency over how the models behave - especially when fine-tuning output for specific use cases. It works well out of the box, but getting very precise/personalised outputs can take some trial and error.
What problems is the product solving and how is that benefiting you?
Smallest.ai is solving the problem of building fast, reliable voice experiences without having to deal with heavy infrastructure or complex setups. Traditionally, getting speech-to-text or text-to-speech working well, especially in real-time, takes a lot of effort around latency, scaling, and model tuning. Smallest.ai abstracts most of that away.
For me, the biggest benefit has been speed of execution. I can quickly test and ship voice-driven features without worrying too much about performance or backend complexity.

What do you like best about the product?
I love smallest.ai's UI and dashboard. It solves the problem of manually recording voiceovers by providing high-quality audios. I appreciate being able to experiment with tone and accents. Their better pricing and better voices motivated me to switch from Cartesia. The initial setup was very easy, and I managed to generate my first voiceovers in a couple of hours.
What do you dislike about the product?
I think there could be better communication on all the features that they have. Adding a regular update cycle on new features going live would be beneficial.

What do you like best about the product?
Onboarded Voice AI suite for enterprises for a key use case we've had trouble automating, customer support. As a app which allowed for real life competition, we needed to find a way to service customer calls, even during late nights where the gaming situation was very high.
Turns out these guys are able to run agents to handle 24/7 interaction so that was a relief.
