The AI Voice Generation Workflow
How TTS.ai turns text into natural-sounding speech (bằng tiếng Anh).
Write or Paste Your Text
Enter anything from a single sentence to a full article. The AI handles punctuation, numbers, abbreviations, and even SSML markup naturally. Long texts are automatically chunked and stitched together seamlessly.
- Paste articles, scripts, or book chapters
- Smart number and abbreviation handling
- Automatic sentence splitting for long texts
- Support for SSML pauses and emphasis
Choose Model & Voice
Pick from 24+ models optimized for different use cases — Kokoro for fast, high-quality output, Bark for expressive speech with sound effects, Tortoise for studio narration quality, or Parler for text-described custom voices. Each model offers multiple built-in voices.
- Preview voices before generating
- Filter by language, gender, and style
- Clone your own voice with a 10-second sample
- Describe a voice in text (Parler TTS)
AI Processing on 4x Tesla P40
Your text is processed on our dedicated GPU cluster with 96GB of VRAM. The neural network analyzes your text for context, prosody, and emotion, then generates a high-fidelity audio waveform. Most requests complete in 2-10 seconds depending on length and model.
- 4x NVIDIA Tesla P40 GPUs (96GB VRAM)
- Priority queue for paid users
- Async processing for long texts
- 24/7 availability
