How to Use

1) Choose a Voice (voice_id)

Use either a custom voice you trained (voice cloning) or a built-in system voice (case-sensitive):

Wise_Woman, Friendly_Person, Inspirational_girl, Deep_Voice_Man, Calm_Woman,
Casual_Guy, Lively_Girl, Patient_Man, Young_Knight, Determined_Man, Lovely_Girl,
Decent_Boy, Imposing_Manner, Elegant_Man, Abbess, Sweet_Girl_2, Exuberant_Girl

2) Set Audio Parameters (mapped to the UI dropdowns)

  • english_normalization (boolean) Improves English text normalization, especially numbers/units (e.g., “$1,299” → “one thousand two hundred ninety-nine dollars”).
  • sample_rate (Hz) 22050 / 24000 / 44100 / 48000. Tip: 44.1 kHz for music/podcasts; 48 kHz for video.
  • bitrate (bps for MP3/OGG) 64k / 96k / 128k / 192k / 256k / 320k. Tip: ≥192k for distribution; 96–128k for previews.
  • channel: mono or stereo Mono is smaller/clearer for speech; stereo for spatial mixes.
  • format: mp3, wav, ogg, flac, wav is lossless (larger); mp3 is compact and web-friendly. Also supports streaming PCM output for real-time playback.
  • language_boost (IETF code: en, zh, ja, …) Prioritizes a primary language in mixed-language inputs.

Prosody controls

  • speed: speaking rate (e.g., 0.8–1.2)
  • volume: gain (linear or dB, depending on API)
  • pitch: pitch shift (semitones/cents or normalized)

Pricing

  • Price: $0.10 / 1,000 characters

Quick examples

  • 1,000 chars → $0.10
  • 2,500 chars → $0.10 × 2.5 = $0.25
