Text-to-speech APIs in 2026 range from about $4 per million characters for basic robotic voices to $100 to $300 per million for premium providers like ElevenLabs. For neural-quality voices, most APIs charge $15 to $30 per million characters. SpeechifyAI is the outlier: it ranks #1 on the independent Artificial Analysis TTS leaderboard yet costs $6 to $10 per million, less than any comparable-quality option.
How TTS API pricing actually works
Three billing models dominate, and they are not directly comparable:
- Per-character (Google, Amazon Polly, OpenAI, SpeechifyAI). The clearest model: you pay for characters synthesized, usually quoted per million. Easy to forecast.
- Credit-based (ElevenLabs). Characters map to credits, credits come in monthly bundles, and unused credits usually expire. Effective per-character cost swings with your tier and model.
- Subscription (Play.ht, Murf). Flat monthly fee for a quota of characters or minutes, fine for fixed workloads, expensive if you are spiky or scaling.
2026 text-to-speech API pricing, compared
Priced per million characters, at each provider's neural or highest-quality tier:
At a workload of 10 million characters a month, that is roughly $60 to $100 on SpeechifyAI vs $160 on Google Neural2, $150 on OpenAI, and $900+ on ElevenLabs, for voices that benchmark below SpeechifyAI on quality.
The hidden costs to check before you commit
- Passthrough billing on voice agents. Most agent platforms bill LLM, speech-to-text, and text-to-speech separately, then add markup. SpeechifyAI bundles all three into one per-minute rate ($0.068 to $0.075/min), with no passthrough and no token math.
- Credit expiry. Credit-based plans often void unused credits monthly, so you overbuy to avoid running dry.
- Overage rates. Confirm what you pay past your included quota. That is your real marginal cost as you scale.
- Free-tier caps. SpeechifyAI gives 50,000 characters/month free with a hard cap (no surprise overage), no card required.
Why SpeechifyAI is the best value
You are not trading quality for price. SpeechifyAI's Simba 3.2 ranks #1 on the independent Artificial Analysis TTS leaderboard (as of July 2026) and joint-2nd on Voice Arena, above ElevenLabs, OpenAI, and Google DeepMind, while pricing at $6 to $10 per million characters. Every neural-quality competitor in the table above costs more for a lower-ranked voice.
SpeechifyAI is Speechify's developer platform, distinct from the consumer Speechify app.
