Frequently Asked Questions for Text to Speech APIs
Common questions about using the Text to Speech API on Pixazo.
What is a Text to Speech API?
A Text to Speech API is a cloud service that converts written text into natural-sounding audio using neural voice synthesis. Pixazo API provides access to multiple TTS models through a single endpoint, letting developers generate realistic speech in 100+ languages without managing infrastructure.
Which AI models are available for text to speech generation?
Pixazo API offers access to Chatterbox, VibeVoice, XTTS, and other leading TTS models through one unified endpoint. Each model has different strengths for naturalness, speed, language coverage, and voice cloning. Compare models on the page above to find the best fit.
How much does the Text to Speech API cost?
Pricing is per character synthesised and varies by model. There are no monthly minimums or setup fees. You only pay for actual usage. Volume discounts are available for high-throughput applications. Check each model card above for specific per-character rates.
What audio formats and quality does the Text to Speech API support?
The Text to Speech API outputs MP3, WAV, OGG, and AAC formats with configurable sample rates from 16kHz to 48kHz. Choose the format and bitrate that matches your platform, whether mobile apps, web players, IVR systems, or broadcast-quality production.
Can I use the generated speech commercially?
Yes. All audio generated through the Text to Speech API is fully licensed for commercial use including audiobooks, podcasts, advertisements, e-learning courses, IVR systems, and digital products. No additional licensing fees or attribution required.
How fast is the Text to Speech API response time?
Most models support real-time streaming, so audio playback begins within milliseconds of the request. Full synthesis of a 1000-word document typically completes in 1 to 2 seconds. Streaming mode is ideal for chatbots, voice assistants, and live applications.
Do I need to train or fine-tune any models for the Text to Speech API?
No training or fine-tuning is required. All TTS models are pre-trained and ready to use immediately via the API. Simply send text and receive audio. Some models support voice cloning from a short audio sample for custom brand voices.
How do I get started with the Text to Speech API?
Sign up for a Pixazo API key, pick a TTS model from the list above, and make a POST request with your text. The API returns an audio file URL or stream. No SDK installation required. Works with any language that supports HTTP requests.
