Voice 40 thirty-second Spanish radio and social spots a month, three takes each. The ads run for a client, so commercial rights are required. Required: commercial rights; Spanish.

What evidence would settle it

The three conditions and what is missing

Vendor claims about their own quality count for nothing in the score. A rating needs a listening test with raw results, or a licensed source that allows reuse.

  • Measure quality for Neural voices, Sonic 3.6, Aura-2, Flux TTS, Eleven Flash, Eleven v4 and 20 more: Naturalness in blind listening (% of blind pairwise votes won against the board's reference voice); Pronunciation errors (mispronounced words per 1,000 words). At least one auditable or documented measurement per option.
  • Name at least two options that are measured. Today 0 are.

The three conditions for naming a best option

  1. The leader's lower bound must exceed every other option's upper bound by at least 3 points. Not assessed.
  2. Every critical metric must come from two independent origins, or from one auditable test of our own. Not assessed.
  3. The price must be verified within 30 days. Not assessed.

Sources and limits

11 sources, the method notes and this board as JSON

No quality score is published on this board. Prices are facts read from each vendor's page and link back to it.

Notes on this board. No quality evidence is published yet: the rights register has no usable source for voice quality (see the Sources page). The board shows cost only and ranks nobody until measured or licensed evidence arrives. Quality metrics and anchors are editorial and unvalidated.

Scores are on a 0 to 100 scale against editorial anchors that are not yet validated. Prices are for the workload above and change without notice. Evidence older than 60 days is left out, and prices older than 30 days are flagged.
