AI media transcription service built for modern broadcast workflows

Getting started with Speechmatics takes just a few clicks. You can upload audio files or video files directly through our portal, or send them to our API programmatically at scale. Once uploaded, our AI transcription engine processes your content and returns an accurate transcribed text file, in your chosen format and language, without any manual effort on your end. For teams handling large volumes of recordings, batch processing lets you queue multiple files and retrieve results automatically.

Human transcription services are slow, expensive, and don't scale. A human transcriber typically processes audio at four to five times its running length, meaning an hour of video content takes four or more hours to manually transcribe. Speechmatics' AI-powered transcription processes the same hour of audio in a fraction of the time, at a fraction of the cost, with accuracy that matches or outperforms manual transcription on most content types. For media companies handling large volumes of recordings across multiple languages, the difference in speed and cost reduction is transformative. Human review remains valuable for highly specialized content, but for the vast majority of media transcription needs, AI transcription is the smarter default.

Yes, and it's one of the most common reasons media companies choose us. Speechmatics can automatically generate subtitles and closed captions for both pre-recorded video content and live broadcasts. Our real-time transcription delivers captions in under one second of latency for live events, while our batch transcription handles post-production captioning across 55+ languages. Subtitles and captions can be exported in standard broadcast formats ready to drop into your workflow. Content accessibility is no longer a manual afterthought, with Speechmatics, it's built in from the start.

Speechmatics supports a wide range of audio and video file formats, including MP4, MP3, WAV, AAC, FLAC, MOV, and more. Whether you're working with raw studio recordings, broadcast archives, phone calls, or streamed video files, our transcription engine handles the input without requiring conversion. If you're integrating via our API, audio is streamed directly, no need to upload a file at all for real-time use cases. Our platform is designed to fit into existing media workflows without adding friction.

Speechmatics is purpose-built for the demands of live captioning at scale. Our real-time transcription delivers accurate, low-latency transcriptions in under one second, fast enough for live broadcast, live streaming, and live events where captions need to keep up with spoken words in real time. AI-Media, one of the world's largest captioning companies, uses Speechmatics to deliver 120x more captioned content than traditional methods allow. Whether you're broadcasting a sporting event, a news program, or a live conference, Speechmatics scales to meet the moment without compromising accuracy.

Significantly more accurate. Basic transcription tools, often built on generic speech recognition models, struggle with accents, background noise, fast speech, and domain-specific vocabulary. Speechmatics uses advanced algorithms and machine learning trained on a diverse, multilingual dataset that consistently delivers high accuracy across challenging real-world audio conditions. In independent benchmarks, Speechmatics produces 25% fewer errors than Microsoft and outperforms other leading providers. For media companies where transcription accuracy directly affects caption quality, content searchability, and compliance, that margin matters.
