Core text speech 2.5 Features

Technical highlights that make the 2.5 HD preview model a leader in synthetic voice technology.

Native Expressive Prosody

The model automatically interprets text context to add natural pauses, sighs, and emotional depth without manual SSML tags.

Zero-Shot Voice Cloning

Replicate any target voice with 94% similarity using only a 5-second sample, supporting cross-lingual synthesis.

Studio-Grade 48kHz Audio

High-definition output designed for broadcasting, providing superior clarity compared to 24kHz standard models.

Sub-200ms Latency

Optimized processing pipeline ensures rapid TTFB, making it the fastest choice for conversational AI applications.

text speech 2.5 FAQ

Common questions about integrating text speech 2.5 into your applications for high-quality audio production.

What is the typical latency for text speech 2.5 requests?

The model is optimized for high-speed performance, delivering a Time To First Byte (TTFB) of approximately 180ms. This makes the text speech 2.5 model significantly faster than OpenAI TTS-1-HD, providing a seamless experience for real-time voice assistants and interactive applications that require immediate verbal feedback.

How long of an audio sample is needed for voice cloning?

To achieve high-fidelity zero-shot voice cloning, you only need a 5 to 10-second audio reference. The text speech 2.5 system uses this sample to extract vocal characteristics, allowing the cloned voice to read any text input with high similarity (94.1%) across 30+ supported languages while maintaining the original speaker's identity.

Does text speech 2.5 support high-definition output?

Yes, it supports studio-grade 48kHz output in various formats including MP3, WAV, PCM, and Opus. This resolution is superior to the 24kHz industry standard, ensuring that synthesized speech sounds professional and clear, which is essential for podcasts, audiobooks, and high-end digital human animations.

What are the input limits for text synthesis?

Each individual request can process text up to 4,096 characters. For longer documents or extensive scripts, we recommend chunking the text into smaller segments. This prevents processing timeouts and ensures the neural engine maintains consistent prosody and emotional inflection throughout the entire audio generation process.

Is my text data used to train the underlying models?

Privacy is a core priority. Any text or audio samples sent through our API to the text speech 2.5 preview model are excluded from ByteDance's training datasets by default. Your proprietary scripts and voice cloning data remain secure and are used solely for generating your specific request outputs.

How does pricing work for HD and cloned voices?

Standard voice synthesis is priced at $15.00 per 1 million characters. For high-definition or cloned voices, the rate is $30.00 per 1 million characters. GPTProto.com provides unified billing, allowing you to access these advanced features without managing multiple separate enterprise contracts with individual vendors.
