MiniMax Speech 2.8 Turbo

$0.1266/1K chars

Overview

MiniMax Speech 2.8 Turbo is the faster, cheaper tier of MiniMax's speech family. Like the HD tier it accepts arbitrary MiniMax voice IDs rather than a fixed catalogue, so you keep the same voice flexibility at a lower price per character.

Usage

All media models use the async job queue. Submit a job, then poll for the result.

Step 1: Submit Job

const res = await fetch('https://api.yepapi.com/v1/media/queue', {
  method: 'POST',
  headers: {
    'x-api-key': 'YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'minimax/speech-2.8-turbo',
    prompt: 'Your text to speak goes here.',
    options: { voice: 'English_expressive_narrator' },
  }),
});
const { data } = await res.json();
// data.jobId — use this to poll for results

curl -X POST https://api.yepapi.com/v1/media/queue \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "minimax/speech-2.8-turbo", "prompt": "Your text to speak goes here."}'

Step 2: Poll for Result

const status = await fetch(`https://api.yepapi.com/v1/media/status/${data.jobId}`, {
  headers: { 'x-api-key': 'YOUR_API_KEY' },
});
const { data: job } = await status.json();
// job.status — "pending" | "processing" | "completed" | "failed"
// job.result.audio — { mimeType, base64 } when completed

curl https://api.yepapi.com/v1/media/status/JOB_ID \
  -H "x-api-key: YOUR_API_KEY"

Write the audio to a file:

import { writeFileSync } from 'node:fs';

writeFileSync('speech.mp3', Buffer.from(job.result.audio.base64, 'base64'));

Request Body

Parameter	Type	Required	Description	Default
`model`	`string`	Yes	`minimax/speech-2.8-turbo`	—
`prompt`	`string`	Yes	The text to speak (max 50,000 bytes)	—

Voices

This model accepts any MiniMax voice ID rather than a fixed catalogue. An explicit voice is required upstream; YepAPI sends English_expressive_narrator when you omit it.

Common IDs:

English_expressive_narrator
male-qn-qingse
female-shaonv

Features

Faster and 40% cheaper than the HD tier
Accepts arbitrary MiniMax voice IDs
Multilingual output
An explicit voice is required — there is no provider default

Billing

Speech is billed on the length of the input text, in UTF-8 bytes — for English text one byte is one character. The cost is known before synthesis starts, so the balance check at submit time quotes the exact final charge. Jobs have a $0.01 minimum.
