The job · requires English

Narrate one 10-hour English book a month in a single voice. Resale is not assumed here; the YouTube and ad boards require commercial rights. Required: English.

Nobody is ranked. Not plotted. Quality has not been measured, so the list below is cost only and not an order of merit.

Cost for this job

Cheapest qualifying plan per month, in USD per month, cheapest first within each group. Not in order of merit; says nothing about quality.

Workload and assumptions

Workload: 600,000 characters a month (low scenario 300,000). One 10-hour book = 600 minutes = 600,000 characters. The low case is a 5-hour title. 1,000 characters per finished minute of audio (assumption: ElevenLabs lists about $0.08 per minute at $0.08 per 1,000 characters; Inworld says about 1,000; Cartesia says 750 to 800).

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-1, Aura-2, Flux TTS, Eleven Flash and 21 more: Naturalness in blind listening (% of blind pairwise votes won against the board's reference voice); Pronunciation errors (mispronounced words per 1,000 words); Voice stays the same over a chapter (mean listener rating, 1 (drifts) to 5 (steady)). 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.
