xAI TTS v1 — Reelina AI Audio
The text to convert to speech. Maximum 15,000 characters. Supports inline instant tags (e.g. [pause]) and wrapping style tags (e.g. <whisper>text</whisper>).
BCP-47 language code or 'auto' for automatic language detection. Case-insensitive.
Voice identifier. Multilingual voices (ara, eve, leo, rex, sal) support all languages; other voices are optimized for their native language and will cascade-update the language field.
Audio codec for the output.
Sample rate in Hz. Supported values: 8000, 16000, 22050, 24000, 44100, 48000.
Bit rate in bps. Applies to MP3 codec only. Supported values: 32000, 64000, 96000, 128000, 192000.
Speech speed multiplier. 1.0 is normal speed. Values below 1.0 slow down speech, values above 1.0 speed it up. Range: 0.7 to 1.5.
Enable text normalization before synthesis. When enabled, the model normalizes written-form text (e.g. numbers, abbreviations, symbols) into spoken-form before generating audio.
Latency optimization level for streaming synthesis. 0 (default): No optimization — best audio quality. 1: Reduced first-chunk size for lower time-to-first-audio, with minor quality tradeoff at chunk boundaries. 2: Further reduced first-chunk size for lowest time-to-first-audio, with more noticeable quality tradeoff at chunk boundaries.
