Frequently asked about ReazonSpeech

Does ReazonSpeech work on Mac, Windows and Linux?

How do I install ReazonSpeech?

Download the installer for your platform from the vendor. No terminal needed.

How many languages does ReazonSpeech support?

ReazonSpeech lists 1 languages.

Does ReazonSpeech identify different speakers?

No. ReazonSpeech does not label speakers; a conversation comes back as one continuous text. If you need speaker labels, that is a separate tool or a different service.

Does ReazonSpeech give word-level timestamps?

Can ReazonSpeech transcribe live audio?

Is ReazonSpeech HIPAA compliant?

ReazonSpeech does not claim HIPAA compliance. For PHI, run it on infrastructure you control or choose a service that will sign a BAA.

What are the limitations of ReazonSpeech?

CDLA-Sharing-1.0 license · Japanese broadcast TV → strict source rights · research-friendly but copyright complex. Cite: Yin et al., NLP 2023.

Does ReazonSpeech run offline?

ReazonSpeech runs on your own machine — it is open source, so nothing leaves the computer unless you configure it to.

Can I use ReazonSpeech in the browser?

No — ReazonSpeech is a HuggingFace application, not a web app. You install it rather than sign in to it.

Where is the ReazonSpeech source code?

Can I automate ReazonSpeech-style transcription without running it myself?

Yes. If what you want is transcripts rather than the tool itself, Whipscribe does the same job as a hosted API: submit a file or URL, poll a job id, pull the result as txt, json, srt, vtt or docx. $0.012 a minute — about $0.72 an audio hour — bought as credits that never expire. The automation recipes on this site show it wired to Drive folders, Zoom recordings, S3 buckets and no-code platforms.

Whipscribe is a hosted transcription service. If you want transcripts without running infrastructure, paste a URL or drop a file in the form below — you'll have a transcript in seconds.
