API README

Speech 02 HD

Speech 02 HD is built for expressive speech synthesis, with this exact route focused on voice and delivery control. Speech 02 Hd by MiniMax - convert text to natural-sounding speech with AI. Supports multiple voices, languages, emotions, and speaking styles for content creation and accessibility. It is designed for production workflows that need a clearly scoped media operation instead of a generic assistant response, preserving the supplied direction while returning an artifact ready for review, iteration, or downstream assembly.

The request surface keeps creative direction and delivery choices explicit through text, audio_setting, output_format, voice_setting, language_boost, pronunciation_dict. Teams can lock source material, describe the intended result, choose supported output controls, and rerun the same request structure across variations. This makes experiments easier to compare and larger pipelines easier to operate without hiding important decisions inside an opaque preset.

Highlights

Voice And Delivery Control. The minimax/speech/02-hd route is dedicated to voice and delivery control, keeping inputs and outputs matched to this operation.
Multilingual Spoken Content. Within minimax/speech/02-hd, documented prompt and media controls direct multilingual spoken content while keeping the brief close to the result.
Natural Long-Form Narration. The minimax/speech/02-hd result provides natural long-form narration in a machine-consumable form for review and downstream production.
Route-specific control. For minimax/speech/02-hd, documented controls include text, audio_setting, output_format, voice_setting, language_boost, pronunciation_dict, defining the supported variation space for this exact route.

When to Use

Scenario	Why it fits
Choose this route	When the deliverable is specifically voice and delivery control, not a neighboring generation or editing task.
Production iteration	When creative teams need repeatable multilingual spoken content with an explicit request payload.
Automated pipelines	When natural long-form narration must flow into review, storage, compositing, or publishing.
Controlled variations	When a stable brief should be rerun while changing only documented inputs.
Prototype to scale	When the same `minimax/speech/02-hd` contract should serve a single experiment and a larger batch later.

Prompt Guide

Lead with the subject or source, then state the transformation, important spatial or temporal details, style, and finish. Supply only documented fields, keep media URLs reachable, and vary one control at a time when comparing outputs.

{
  "text": "A directed creative request with subject, setting, style, motion, and finish.",
