​
Path Parameters

​
project_id
string
required
The unique identifier of the project to re-translate.

​
Request Body

​
target_script
array
required
Array of target language script segments for dubbing.Timing and Speaker Behavior:
  • Speaker assignments are required - Each speaker_id must correspond to a speaker in target_speakers. If not specified, the request will be rejected with validation error
  • Timings may be modified - System adjusts timings to match synthesized speech length and avoid excessive speed changes, unless use_fixed_timings: true is set
​
target_speakers
array
required
Array of target speaker configurations for dubbing.
​
mixing_mode
string
default:"voiceover_with_original_track"
Audio mixing mode:
  • voiceover_only - Only voiceover without the original track
  • voiceover_with_original_track - Voiceover with the original track
  • voiceover_without_original_voice - Smart vocal removal dubbing
​
use_fixed_timings
boolean
default:"false"
Whether to use fixed timings from the target script. By default, timings may be adjusted to fit the original video better.
​
tts_volume
string
default:"normal"
TTS volume level: very_quiet, quieter, normal, louder, very_loud.

​

Getting Original Script Data

Use Get Project to retrieve the original output_source_script, output_target_script, and output_target_speakers as starting points for your re-translation.

​
Timing Considerations

  • start_ms and end_ms should align with natural speech boundaries
  • Large timing changes may affect lip-sync quality
  • Use use_fixed_timings: true to prevent automatic timing adjustments

​
Voice Selection

  • Use specific voice keys from Get Voices for consistent results
  • soundalike voices attempt to match original speaker characteristics
  • emotional_transfer provides more expression but may be less stable
