Transcription Options
A number of transcription options are available.
V2 ASR model
The v2 ASR model is our latest, most advanced ASR model. It represents an entirely new architecture that promises 10-15% relative improvement in accuracy.
The v2 ASR model supports English only and has full feature parity with our older v1 ASR model. It is our recommended model for all ASR transcription requests.
V1 ASR model
The v1 ASR model is our older ASR model, now available only to some users and for a limited period of time.
Default model
For new pay-as-you-go (PAYG) and enterprise user accounts created after July 25, 2022, the default transcription model is the v2 ASR model.
For existing PAYG user accounts, the default transcription model is:
- the v1 ASR model until Aug 25, 2022
- the v2 ASR model after Aug 25, 2022
For existing enterprise user accounts, the default transcription model is:
- the v1 ASR model until Jan 25, 2023
- the v2 ASR model after Jan 25, 2023
When no transcriber option is provided, or if the transcriber option is set to machine, transcription will be performed by the default model in effect for the user at the given time.
When the transcriber option is set to machine_v2, transcription will always be performed by the
v2 ASR model, regardless of the default model in effect.
attention
The transcriber option is ignored for non-English transcription requests.
Early migration
Existing PAYG and enterprise users can request early migration to the new v2 ASR model by contacting the support team (for PAYG accounts) or contacting their account representative (for enterprise accounts).
Deferred migration
For a limited transition period, existing PAYG and enterprise users can request continued usage of the older v1 ASR model as default by filling a request form (for PAYG accounts) or contacting their account representative (for enterprise accounts).
Summary
The above information is summarized in the following table:
| Migration date | Default model1 before migration date | Default model1 after migration date | No transcriber OR transcriber: machine | transcriber: machine_v2 | |
|---|---|---|---|---|---|
| PAYG / enterprise account created on / after Jul 25, 2022 | N/A | v2 | v2 | Default model | v2 model |
