Amazon Transcribe is an automatic speech recognition service that makes it easy to add speech to text capabilities to any application. Transcribe’s features enable you to ingest audio input, produce easy to read and review transcripts, improve accuracy with customization, and filter content to ensure customer privacy.

Audio inputs

Transcribe is designed to process live and recorded audio or video input to provide high quality transcriptions for search and analysis. We also offer separate APIs that uniquely understand customer calls (Amazon Transcribe Call Analytics) and medical conversations (Amazon Transcribe Medical).

Streaming & batch transcription

You can process your existing audio recordings or stream the audio for real-time transcription. Using a secure connection, you can send a live audio stream to the service, and receive a stream of text in response.

Audio inputs

Domain specific models

Select a model that is tuned to telephone calls or multimedia video content. For example, Transcribe adapts to low-fidelity phone audio common in contact centers.

Automatic language identification

With Amazon Transcribe, you can automatically identify the dominant language in an audio file and generate transcriptions. This is useful when your media library contains audio files in different languages. You can also use this feature for media content classification and verify that the main spoken language in your videos and podcasts is correctly labeled.

Easy to read transcripts

Amazon Transcribe enables you produce accurate transcripts that are easy to read, review, and integrate into your specific applications. We work to make the output ready for downstream activities such as call transcript analysis, subtitling, and content search.

Punctuation & number normalization

Amazon Transcribe automatically adds punctuation and number formatting, so that the output closely matches the quality of manual transcription at a fraction of the time and expense. Numbers are also transcribed into digits or “normal form” instead of words.

Easy to read transcripts

Timestamp generation

Amazon Transcribe returns a timestamp for each word, so that you can easily find a word or phrase in the original recording or add subtitles to video.

Recognize multiple speakers

Speaker changes are automatically recognized and attributed in the text to capture scenarios like telephone calls, meetings, and television shows accurately. To learn more about speaker identification.

Channel identification

Contact centers can submit a single audio file to Amazon Transcribe, and the service will identify produce a single transcript annotated by channel labels automatically.

Customize your output

Accuracy is critical and we provide you many options to customize transcripts to your specific business needs and vernacular. Transcribe also provides up to 10 alternative transcriptions for each sentence, so you can quickly choose the best option that applies to your content and domain. This is useful for human in-the-loop subtitling workflows.

Custom vocabulary

With custom vocabulary, you can add new words to the base vocabulary to generate more accurate transcriptions for domain-specific words and phrases like product names, technical terminology, or names of individuals.

Customize your output

Custom language models

When needed, you can build and train your own custom language model (CLM) for your use case and domain by submitting a corpus of text data to Amazon Transcribe. CLM is a suitable feature for enhancing speech recognition accuracy with your own data.

User safety & privacy features

Ensuring customer privacy and safety is critical. When needed, Transcribe enables you to mask or remove words that are sensitive or unsuitable for your audience from transcription results.

Vocabulary filtering

You can specify a list of words to remove from transcripts with vocabulary filtering. For example, you can specify a list of profane or offensive words and Amazon Transcribe removes them from transcripts automatically.

User safety & privacy features

Automatic content redaction / PII redaction

When instructed, Amazon Transcribe can help customers identify and redact sensitive personally identifiable information (PII) from the supported language transcripts. This allows contact centers to easily review and share the transcripts for customer experience insight and agent training.

Amazon Transcribe Call Analytics

Extract conversation insights like call sentiment and speech loudness to improve agent productivity and customer experience with Amazon Transcribe Call Analytics.

Extract detailed call analytics & conversation insights

Using the power of machine learning, you can quickly apply speech-to-text and natural language processing capabilities to uncover valuable conversation insights. You can then integrate insights such as customer and agent sentiment, detected issues, and speech characteristics like non-talk time, interruptions, and talk-speed into your inbound and outbound call analytics applications. This can help your supervisors more readily identify potential customer issues, agent coaching opportunities, and call trends.

Amazon Transcribe Call Analytics

Improve compliance & monitoring with automated call categorization

Monitor your calls at scale to track compliance with company policies or regulatory requirements. Build and train your own custom categories based on your specified criteria (e.g. words/phrases or conversation characteristics). For example, you can setup category labels to see what percentage of calls are upsells or account cancellation.

Produce rich call transcripts

Give your agents access to the conversation details from past interactions. The turn-by-turn transcripts provide insights such as customer sentiment, detected issues and interruptions.

Protect sensitive customer data

Conversations often contain sensitive customer data such as names, addresses, credit card numbers, and social security numbers. Transcribe Call Analytics helps customers identify and redact this information from both the audio and text.
