Alternatives to YODAS

Frequently asked about YODAS

Does YODAS work on Mac, Windows and Linux?

YODAS runs on HuggingFace. It is not listed for other platforms; check the vendor for anything beyond HuggingFace.

How do I install YODAS?

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

How many languages does YODAS support?

YODAS lists 140 languages. That is the Whisper-family multilingual set, so quality varies by language — English and the large European languages are strongest.

Does YODAS identify different speakers?

No. YODAS 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 YODAS give word-level timestamps?

Yes — YODAS produces timing per word, which is what subtitle cues and clip boundaries need.

Can YODAS transcribe live audio?

No — YODAS works on finished files, not a live stream.

Is YODAS HIPAA compliant?

YODAS 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 YODAS?

CC BY 3.0 (subtitles) but underlying YouTube videos are individually-licensed · video access subject to YouTube TOS · per-language quality varies hugely. Cite: Li et al., ASRU 2023.

Who is YODAS best for?

Massive multilingual self-supervised pretraining; ASR pretraining for low-resource languages.

Does YODAS run offline?

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

Can I use YODAS in the browser?

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

Where is the YODAS source code?

On GitHub at github.com/espnet/yodas. It is maintained by CMU / WAVLab.

What kind of tool is YODAS?

In this directory YODAS is filed under dataset as a open-source tool.

What are the alternatives to YODAS?

There is a side-by-side page at /tools/yodas-alternatives comparing YODAS with the closest tools in the same category on price, platform and features.

Can I automate YODAS-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.
