Google Cloud TTS
Google Cloud Text-to-Speech is a production-grade TTS API with one of the widest language and voice selections: 380+ voices across 50+ languages. The Chirp 3 HD tier (launched January 2026, $30/1M chars) significantly closed the quality gap with ElevenLabs on naturalness and prosody. Four tiers: Standard/WaveNet ($4/1M, dated quality), Neural2 ($16/1M, solid), Chirp 3 HD ($30/1M, flagship), and Studio ($160/1M, premium). Also offers custom voice creation and Gemini-TTS for token-priced synthesis. Best for teams deeply integrated with GCP, applications requiring broad multilingual coverage, or global products where 50+ language support is a hard requirement.
Standard/WaveNet: $4/1M chars. Neural2: $16/1M. Chirp 3 HD: $30/1M. Studio: $160/1M. Free tier: 1M chars/mo (WaveNet) or 100 chars/mo (custom voice). Pay-as-you-go.
