Build with Free, Unlimited MiniMax TTS All Week on Vapi
High-quality TTS is a core part of a great voice agent, but the cost of experimentation is a major bottleneck. Finding the right voice for your use case often means cycling through different models and styles, which can get expensive before you’ve even shipped a prototype.
For one week, we’re removing that barrier.
We've partnered with MiniMax to give the Vapi community free, unlimited, and unrestricted access to their entire TTS library. This is a chance to test their production-grade voices on our sub-500ms infrastructure without any cost constraints.
Here’s what the Vapi x MiniMax API week includes:
- Free TTS for a Week: From today until 22nd Sept, get unlimited access to all MiniMax TTS models directly through the Vapi API and your dashboard.
- A 20% Discount for a Year: Any developer who uses the MiniMax model this week will receive a 20% discount on MiniMax API usage for the next year.
- $10 Vapi Credit: Use the code below to get $10 in Vapi credits to cover any platform usage while you experiment:

Getting the Best Performance from MiniMax on Vapi
To help you get the most out of the week, here are some recommendations for configuring their models on our platform.
1. Language Configuration
The MiniMax Speech-02-turbo model supports over 40 languages. While the auto setting for language_boost works well, we recommend selecting a specific language tag for specialized use cases (e.g., Thai, Japanese) to achieve the best results.
Path: Assistant → Voice → Language
Path: Workflow → Global Voice → Language
Path: Conversation → Voice → Language
2. Text Normalization
To ensure proper pronunciation of numbers, emails, and dates in customer service scenarios, enable text normalization. This feature is on by default, and we recommend keeping it active.
Path: Voice → Additional Configuration → Text Normalization
3. Pre-Trained Voice Library
If you don’t need a custom clone, we have integrated a default library of high-quality, pre-trained MiniMax voices. Simply select your preferred option from the Voice List in your settings to get started quickly.
This is a great opportunity to experiment with new voices and build something new.
