Technical Principles Behind MooER
Deep Learning Architecture
MooER employs deep learning techniques, particularly neural networks, to process and understand voice signals.
End-to-End Training
The model operates directly from raw voice signals to text output, eliminating the need for multiple independent modules typically found in traditional speech recognition systems.
Encoder-Adapter-Decoder Structure
- Encoder: Converts input voice signals into a series of high-level feature representations.
- Adapter: Adjusts and optimizes the model’s adaptability to specific tasks, enhancing generalization capabilities.
- Decoder (Large Language Model, LLM): Generates the final text output based on these features.
LoRA Technology
MooER uses LoRA (Low-Rank Adaptation), a parameter-efficient model fine-tuning method that updates only a small part of the model’s parameters to improve training efficiency and results.
Pseudo-Label Training
The model utilizes pseudo-label technology during training, where the model’s predictions are used as training data to enhance learning capabilities.
Multilingual Support
MooER supports speech recognition in both Chinese and English, as well as Chinese-to-English speech translation, showcasing its multilingual processing abilities.
