Lightning V3.1 is our most natural-sounding TTS model to date, based on neutral third-party and customer evaluation. It supports 15 languages: English, Spanish, French, Italian, Dutch, Swedish, Portuguese, German, Hindi, Tamil, Kannada, Telugu, Malayalam, Marathi, and Gujarati, with automatic language detection and mid-sentence language switching.
Lightning V3.2 extends the V3 architecture with instruction-following capability. The model accepts explicit directives for emotional register, pitch variation, and volume control, including low-energy output states like whispering that are difficult to achieve through prosody modeling alone.
