}MiniMax’s high-definition text-to-speech model, Compared to Speech 02 released in May, Speech 2.6 has three major breakthroughs: stronger multilingual expressiveness, more accurate voice replication, and broader coverage with 40 languages.
Best suited for long-form text-to-speech generation, such as entire books. Task queue times may be longer. For short sentence generation, voice chat, or online social scenarios, we recommend using synchronous TTS.
Request Headers
string

number
Range: [0.5, 2], default is 1.0.Controls the speech rate of the generated audio. Optional. Higher values result in faster speech.
number
Range: (0, 10], default is 1.0.Controls the volume of the generated audio. Optional. Higher values result in louder audio.
number
default:0
Range: [-12, 12], default is 0.Controls the pitch of the generated audio. Optional. 0 means original timbre. The value must be an integer.
string
The requested voice ID.Supports both system voices (ID) and cloned voices (ID). The available system voice IDs are as follows:

list
Replacement of text, symbols and corresponding pronunciations that require manual handling.
Replace the pronunciation (adjust the tone/replace the pronunciation of other characters) using the following format:[“omg/oh my god”]For Chinese texts, tones are replaced by numbers, with 1 for the first tone (high), 2 for the second tone (rising), 3 for the third tone (low/dipping), 4 for the fourth tone (falling), and 5 for the fifth tone (neutral).
string
default:"null"
Enhances recognition of specified minor languages and dialects. Setting this parameter can improve speech performance in the specified language/dialect scenarios. If the minor language type is not clear, you can set it to “auto” and the model will automatically determine the language type. Supported values:
'Chinese', 'Chinese,Yue', 'English', 'Arabic', 'Russian', 'Spanish', 'French', 'Portuguese', 'German', 'Turkish', 'Dutch', 'Ukrainian', 'Vietnamese', 'Indonesian', 'Japanese', 'Italian', 'Korean', 'Thai', 'Polish', 'Romanian', 'Greek', 'Czech', 'Finnish', 'Hindi', 'Bulgarian', 'Danish', 'Hebrew', 'Malay', 'Persian', 'Slovak', 'Swedish', 'Croatian', 'Filipino', 'Hungarian', 'Norwegian', 'Slovenian', 'Catalan', 'Nynorsk', 'Tamil', 'Afrikaans', 'auto'object
Voice FX settings. Supported audio formats for this parameter: mp3, wav, flac
Show properties

integer
Pitch adjustment (darker/brighter). Range: [-100, 100]. Values closer to -100 generate a deeper (darker) voice; values closer to 100 produce a brighter voice.
integer
Intensity adjustment (powerful/soft). Range: [-100, 100]. Values closer to -100 generate a more powerful sound; values closer to 100 result in a softer sound.
integer
Timbre adjustment (magnetic/crisp). Range: [-100, 100]. Values closer to -100 make the voice more full/magnetic; values closer to 100 make it crisper.
string
Sound effect setting (only one may be selected per request). Valid values:
spacious_echo(large space echo)auditorium_echo(auditorium broadcast)lofi_telephone(telephone distortion)robotic(robotic effect)
Response
string
Use the task_id to request the Task Result API to retrieve the generated outputs.
