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

Show Script Object Properties

start_ms · number · required

Start time in milliseconds.

end_ms · number · required

End time in milliseconds.

text · string · required

Text of the translation to synthesize.

speaker_id · number · required

Speaker ID corresponding to target_speakers.

target_speakers · array · required

Array of target speaker configurations for dubbing.

Show Speaker Object Properties

speaker_id · number · required

Unique speaker identifier (must match script speaker_id values).

style · string · required

Speaker style: masculine or feminine.

voice_key · string · required

Voice identifier. Can be:

• soundalike for AI-generated voices matching original speakers
• emotional_transfer for emotional soundalike voices
• Specific voice key from Get Voices

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.

Response

project_id · string

Unique identifier for the project.

cost_minutes · number

Number of minutes charged for this re-translation (typically 0).

estimated_completion_date · string

ISO timestamp of estimated completion time.

balance_minutes · number

Remaining balance in minutes.

translations_count · number

Total number of translations for this project.

Success Response

{
  "project_id": "12345",
  "cost_minutes": 0,
  "estimated_completion_date": "2024-06-05T12:00:00Z",

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
