Gemini 2.5 Pro TTS is live: Google's text-to-speech, 10% below list
google/gemini-2.5-pro-tts/text-to-speech
Google's Gemini 2.5 Pro text-to-speech is now live on SpicyAPI as google/gemini-2.5-pro-tts/text-to-speech.
- Input: a script of up to 5,000 characters. Cues in square brackets such as
[sighs]are performed, not read aloud. - Voice: one of 30 prebuilt voices, each with a fixed character — from bright and firm to breathy and warm.
- Delivery: an optional style (whisper, empathetic, vocalsmile, newscaster, promohype or deadpan), one of 8 English accents, and free-text instructions on pace, mood and who's listening — none of which is spoken aloud.
- Output: one WAV file, 24 kHz, 16-bit mono.
- Price: $0.00045 per second of audio returned (about $0.027 per minute), 10% below Google's list price. A hold for the longest possible clip is placed while the task runs and released once the audio is measured; failed requests are not charged.
How far it goes. We add no content filter. In our tests it read NSFW scripts in full — direct lines, narrated fiction, breathy vocal cues — without skipping words or cutting the clip short. There's no two-voice dialogue on this endpoint and no voice cloning: one voice per request, from the 30 prebuilt options.
