# Lattice-1 |
|
|
|
|
|
**Release Date:** November 30, 2025 |
|
|
|
|
|
## Model Description |
|
|
|
|
|
Lattice-1 is an advanced forced alignment model designed for precise word-level alignment between audio and text. This model provides state-of-the-art performance in aligning speech with its corresponding word transcription, enabling accurate time-stamping of words in spoken language. |
|
|
|
|
|
## Key Features |
|
|
|
|
|
- **High-Precision Alignment**: Achieves accurate word-level forced alignment with millisecond precision |
|
|
- **Multilingual Support**: Supports English, Chinese, and German, with support for mixed-language content |
|
|
- **Efficient Processing**: Optimized for fast inference with ONNX runtime support |
|
|
- **Flexible Integration**: Easy to integrate into various speech processing pipelines |
|
|
|
|
|
## Supported Languages |
|
|
|
|
|
Lattice-1 supports the following languages: |
