Airy TTS Sets Cost-Accuracy Frontier
Airy TTS claims $3.67 per 1M characters and 1.84% WER in Coval’s seven-day snapshot, making it 59% cheaper than the next-lowest-priced model while remaining close to the accuracy leader. Airy offers both a free studio and developer API.[Airy](https://airy.so/) [Coval benchmark](https://benchmarks.coval.ai/benchmarks/word-error-rate)
// ANALYSIS
Airy’s value proposition is compelling: voice developers may no longer need to trade materially better accuracy for dramatically higher inference costs.
- –The reported $3.67/M-character price undercuts the $9 next-cheapest model by 59%.
- –A 0.08 percentage-point WER gap to the leader puts Airy near the practical accuracy ceiling in this snapshot.
- –Coval evaluates TTS intelligibility through transcription with a fixed Whisper model, so WER does not capture naturalness, prosody, voice variety, or emotional range.[Coval methodology](https://benchmarks.coval.ai/overview)
- –Developers should validate latency, concurrency limits, quotas, and long-form voice quality before switching production workloads.
