Speechmatics | Python SDK
Overview
The Speechmatics Python Software Development Kit (SDK) provides a convenient way to integrate the Speechmatics enterprise-grade speech-to-text APIs into Python applications.
The SDK supports modern Python coding practices including async/await patterns, type hints, and utilizes context managers for production-ready code. It encompasses several functionalities including Real-time and Batch transcription, custom vocabularies, speaker diarization, and speaker identification.
The SDK supports numerous languages, making it a flexible tool for developers working on international or multi-language projects. The SDK allows developers to upload audio files for processing and receive transcriptions with timestamps, speakers, and entities.
It supports streaming of audio for live transcriptions. Moreover, the SDK can be used to develop conversational AI applications with features like speaker diarization and turn detection.
Lastly, it includes Text-to-Speech capabilities, allowing developers to convert text to natural-sounding speech in multiple languages, provided both in streaming and batch modes.

Mery🙏 82 karmaMay 16, 2025@AssemblyAIOne of the most accurate API's I've used for speech to text and summarization. Cost effective w/ bulk contracts too. -
Unlimited transcripts, summaries, 99.8% accuracy, speaker recognition, superfastI already have another transcription tool, but this one is much better. I love the different features such as the summary, quiz, and chapters. It does a great job of them. I've only done one transcript so far to try it out, but I'm truly impressed and am going to grab another code. A couple things that would make it even better are: - the ability to rename the files and organize them through folders. - the ability to download a copy of the other features as well as the transcript. Copying and pasting it works, but doesn't keep the format. -
🎯 3 free transcripts every day. 🔥 Unlimited transcription starting at $10/mo.No other tool quite like this, it's pretty straightforward. Needed to extract a long interview from YouTube and it extracted everything, providing it in different meaningful formats in less than two minutes. Awesome
