Editorial preview: vendor recordings and hands-on verdicts are pending. What counts as evidence.
Choose with fewer unknowns.
A plan for your decision, not a product ranking. Mark only what you have verified. Your selections are not submitted or saved; keep a printed copy if useful.
Define latency, concurrency, error handling, billed input units and required output format.
If a check is still open
Find the smallest next step that resolves it. A missing plan fact needs a source or vendor answer. An unknown voice result needs an audition. An unclear permission needs clarification. Checking every box records your assessment; it does not certify a vendor or replace the evidence behind a review.
Keep two questions separate
“Does this tool meet the requirements?” comes before “Which acceptable option costs less?” We have not completed the vendor tests needed to declare a quality winner. Start with the documented Fish Audio and ElevenLabs comparison, and retain alternatives if neither meets your requirements.
