About TTS-1
TTS-1 turns text into spoken audio fast enough for a live conversation. It comes with nine built-in voices, including alloy, nova and shimmer, and returns MP3, Opus, AAC, FLAC, WAV or raw PCM.
Speed is the trade: OpenAI says it is lower quality than its HD sibling, and unlike OpenAI’s newer speech models you cannot direct its tone or accent. For read-aloud features, voice replies and prototypes it is the inexpensive, dependable choice.
What is TTS-1 good for?
- Voice replies in real time.
- Reading app content aloud.
- Low-cost narration and prototypes.
Where to be careful
- Audio quality is below OpenAI’s HD and newer speech models.
- Voices are tuned for English. Other languages work but can sound less natural.
- Up to 4,096 characters per request, so long text has to be split.
