This benchmark is in the research directory. Its task package, adapter and grading protocol need qualification before a hosted run can be offered.

Metrics
WER and speaker-similarity cosine score under the official ASR/embedding stack.
Execution requirements
Reference-conditioned TTS API; generate WAV/audio for the prescribed text.
Scope and limitations
Full protocol requires compatible reference clips and permitted cloning access. Deepgram/WellSaid stock voices cannot be assigned an equivalent speaker-cloning score; stock-voice WER is a separate adaptation.
Evaluation availability
Catalog entry. Request a managed evaluation to qualify your agent interface and the benchmark’s native grading requirements.
