強項
- Elo score of 1188 reflects above-average pronunciation quality and naturalness
- Reliable on standard text passages with lower processing costs compared to leading TTS models
- Capable enough for commercial deployment in applications with moderate quality requirements
弱項
- Not yet top-tier; struggles with complex speech patterns, diverse accents, and regional dialects
- Limited voice modulation flexibility (voice cloning, emotion, prosody)
- Processing speeds can lag behind specialized models, making it less suitable for real-time applications

指南與影片
xAI Grok TTS is xAI's text-to-speech model, accessible via API at docs.x.ai or x.ai/api—send text and receive audio files (MP3, WAV, PCM, mu-law, A-law). The model features 5 voices (Eve, Ara, Leo, Rex, Sal) with automatic language detection across 20+ languages, priced at $4.20 per 1M characters with a limit of 15,000 characters per request. Ideal for building voice agents, producing podcasts, and integrating into client apps or call centers. Pro tip: use inline speech tags in your text to control emotions such as pauses, laughter, whispers, or emphasis—making speech sound significantly more natural than standard TTS. For custom voices, you can create one from a reference audio clip up to 120 seconds long.
