About this API

ElevenLabs is a UK AI voice company founded 2022, quickly becoming the TTS quality benchmark. Differentiator is "realism" — vs. Google/Azure TTS, ElevenLabs voices are nearly indistinguishable from human, with natural emotion, pauses, and intonation. Most popular feature: Voice Cloning — upload 1 minute of you speaking, AI clones your voice for subsequent TTS. Common uses: audiobook production (replacing human narrators), content creator multi-language dubbing (one English YouTuber publishes Spanish version one-click), personalized game NPC voices (no per-NPC voice actors needed). Also used in accessibility (screen readers for visually impaired). Simple API, complete SDKs. Free tier only 10000 chars/month (enough for testing); commercial $5-$330/month tiers.
