Soniox Text-to-Speech is a developer API billed per token, at roughly $0.70 per hour of generated speech. Documented drawbacks: there is no consumer app, token billing needs conversion to estimate a budget, cloned voices must be recomputed when a new model ships, and you need an account and API key.
ElevenLabs starts at $6 per month on Starter (Creative), with 30k credits and about 30 minutes of TTS, and has a free tier. Descript starts at $16 per month per editor on Hobbyist (billed annually, $24 if monthly) and has a free tier; it is an editor with voice features, not an API. Synthesia starts at $29 per month on Starter for 10 minutes of video per month, with a free tier, and produces video rather than raw speech. Each swaps pay-per-use for a fixed monthly plan.

| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Soniox Text-to-Speech (this page) | From $0.7 (Pay as you go) | No | Web, API | It is a developer API with token-based billing that needs conversion to estimate cost, and cloned voices must be recomputed when a new model ships. |
| ElevenLabs | $6/mo (Starter (Creative)) | Yes | Web, API | Everything draws from one monthly credit pool with per-product costs that differ widely (1 credit per TTS character vs 900 per music minute), so budgets need planning. |
| Descript | $16/mo (Hobbyist) | Yes | Desktop, API | Monthly caps on media hours and AI credits; overages require top-ups |
| Synthesia | $29 (Starter) | Yes | Web, API | Downloading videos requires a paid plan, and all usage is metered by credits and minutes. |
