MiniMax Speech (T2A)

The MiniMax speech models are available through Upmore via the standard audio API (/v1/audio/speech). Send text, get audio bytes back — billing is per input character.

Available models

Model	Notes
`speech-2.8-hd`	Latest generation, high fidelity
`speech-2.8-turbo`	Latest generation, low latency
`speech-2.6-hd` / `speech-2.6-turbo`	Previous generation
`speech-02-hd` / `speech-02-turbo`	Legacy
`speech-01-hd` / `speech-01-turbo`	Legacy

hd variants prioritize audio fidelity; turbo variants prioritize latency and cost less. All models share the same request format.

Quick example

curl https://api.upmore.net/v1/audio/speech \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "speech-2.8-hd",
    "input": "你好，欢迎使用语音合成服务。",
    "voice": "male-qn-qingse",
    "response_format": "mp3"
  }' --output speech.mp3

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.upmore.net/v1"
)

response = client.audio.speech.create(
    model="speech-2.8-hd",
    voice="male-qn-qingse",
    input="你好，欢迎使用语音合成服务。",
    response_format="mp3",
)

response.write_to_file("speech.mp3")

import fs from 'node:fs'
import OpenAI from 'openai'

const client = new OpenAI({
  apiKey: process.env.UPMORE_API_KEY,
  baseURL: 'https://api.upmore.net/v1',
})

const speech = await client.audio.speech.create({
  model: 'speech-2.8-hd',
  voice: 'male-qn-qingse',
  input: '你好，欢迎使用语音合成服务。',
  response_format: 'mp3',
})

fs.writeFileSync('speech.mp3', Buffer.from(await speech.arrayBuffer()))

Parameters

Parameter	Type	Required	Description
`model`	string	Yes	One of the model IDs from the table above
`input`	string	Yes	Text to synthesize, billed per character
`voice`	string	Yes	MiniMax voice ID (e.g. `male-qn-qingse`, `female-shaonv`) — not OpenAI voice names
`response_format`	string	No	`mp3` (default), `wav`, `flac`, `aac`, or `pcm`
`speed`	number	No	Playback speed, `0.5` – `2`. Default: `1`
`metadata`	object	No	Provider-specific fields merged into the upstream request

Advanced: provider passthrough

Anything MiniMax’s native T2A API supports can be passed through metadata — the object is merged into the upstream request body:

"metadata": {
  "voice_setting": { "emotion": "happy", "pitch": 0 },
  "audio_setting": { "sample_rate": 32000, "bitrate": 128000 },
  "language_boost": "Chinese"
}

By default the platform returns the audio bytes directly. Set "metadata": {"output_format": "url"} to receive a 302 redirect to a temporary audio URL instead (use curl -L).
