Alternatives to YODAS2
Frequently asked about YODAS2
Does YODAS2 work on Mac, Windows and Linux?
YODAS2 runs on HuggingFace. It is not listed for other platforms; check the vendor for anything beyond HuggingFace.
How do I install YODAS2?
Download the installer for your platform from the vendor. No terminal needed.
How many languages does YODAS2 support?
YODAS2 lists 149 languages. That is the Whisper-family multilingual set, so quality varies by language — English and the large European languages are strongest.
Does YODAS2 identify different speakers?
No. YODAS2 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 YODAS2 give word-level timestamps?
Yes — YODAS2 produces timing per word, which is what subtitle cues and clip boundaries need.
Can YODAS2 transcribe live audio?
No — YODAS2 works on finished files, not a live stream.
Is YODAS2 HIPAA compliant?
YODAS2 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 YODAS2?
Same YouTube + CC BY 3.0 subtitle constraint as YODAS v1. Cite: Li et al., 2024.
Who is YODAS2 best for?
Long-form ASR training (full videos preserved); cross-lingual alignment.
Does YODAS2 run offline?
YODAS2 runs on your own machine — it is open source, so nothing leaves the computer unless you configure it to.
Can I use YODAS2 in the browser?
No — YODAS2 is a HuggingFace application, not a web app. You install it rather than sign in to it.
Where is the YODAS2 source code?
On GitHub at github.com/espnet/yodas2. It is maintained by CMU / WAVLab.
What kind of tool is YODAS2?
In this directory YODAS2 is filed under dataset as a open-source tool.
What are the alternatives to YODAS2?
There is a side-by-side page at /tools/yodas2-alternatives comparing YODAS2 with the closest tools in the same category on price, platform and features.
Can I automate YODAS2-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.
