Best AI Audio Generation APIs
HiAPI exposes audio generation models — text-to-speech (TTS), music, and sound effects — through the same unified POST /v1/tasks endpoint used for image and video. Use one API key and one task model to add voice, music, or audio effects to your product.

Quick comparison
Section titled “Quick comparison”Each audio model is accessed through the same POST /v1/tasks endpoint and returns an audio artifact (for example mp3 or wav) that you can poll for or receive via callback.
| Model | Best for | Endpoint | Notes |
|---|---|---|---|
| ElevenLabs Text to Dialogue v3 API | Multi-speaker dialogue: audio dramas, podcasts, game NPCs | /v1/tasks | 67 preset voices, 70+ languages, per-line voice control; billed per character, up to 5000 characters per call |
| MiniMax Music 1.5 API | Full songs with vocals: soundtracks, jingles, brand music | /v1/tasks | Up to ~4-minute songs, English/Chinese lyrics with structure tags; billed per song |
More audio capabilities are rolling out on the same endpoint:
| Capability | Typical use | Endpoint | Notes |
|---|---|---|---|
| Text-to-speech (TTS) | Voiceovers, narration, assistants | /v1/tasks | Returns a spoken-audio file from input text |
| Music generation | Background tracks, jingles, loops | /v1/tasks | Returns a music clip from a text prompt |
| Sound effects | UI sounds, ambience, foley | /v1/tasks | Returns a short audio effect from a prompt |
New audio models are added continuously. Check HiAPI Pricing for the current model list and live pricing.
How audio APIs work on HiAPI
Section titled “How audio APIs work on HiAPI”Every audio model uses the unified async task flow:
POST /v1/taskswith the audio model id and aninputobject.- Receive a task id.
- Poll
GET /v1/tasks/:id(or use a callback) until the task completes. - Read the audio artifact URL from the completed task, then download or stream it.
Because audio jobs are async, prefer callbacks or moderate polling intervals over tight polling loops.
API key setup
Section titled “API key setup”All audio generation APIs on HiAPI use the same API key and task endpoint. Create one key in API Keys, then pass it with each request:
Authorization: Bearer YOUR_API_KEYKeep the API key on your server. For browser apps, send the user’s text or prompt to your backend first, then create the HiAPI task from there.
Pricing and cost
Section titled “Pricing and cost”Current pricing is maintained on HiAPI Pricing. Audio pricing usually depends on the model and its billing unit — output duration (per second) or input length (per character) — plus request volume.
For cost control:
- Test with short prompts or short text before generating long audio.
- Cache generated audio you expect to reuse.
- Prefer callbacks over aggressive polling.
- Track failed jobs separately so invalid requests do not become hidden retry cost.
What is an AI audio API?
Section titled “What is an AI audio API?”An AI audio API lets your application generate speech, music, or sound effects from text or prompts. HiAPI exposes audio models through POST /v1/tasks, then returns a task id for polling or callback-based completion.
How do I get an AI audio API key?
Section titled “How do I get an AI audio API key?”Create a HiAPI account and generate a key in API Keys. The same key works across audio, image, and video task models.
How much does an AI audio API cost?
Section titled “How much does an AI audio API cost?”Audio API cost depends on the model and its billing unit (per second of output or per character of input) plus request volume. Use HiAPI Pricing for current pricing.
What audio formats does HiAPI return?
Section titled “What audio formats does HiAPI return?”Audio tasks return a downloadable artifact URL, commonly mp3 or wav, depending on the model.
