What is Ichigo?
Ichigo is an open-source multimodal AI voice assistant that employs a mixed-modal model to process interwoven sequences of speech and text in real time. It directly quantizes speech into discrete tokens and uses a unified transformer architecture to process both speech and text simultaneously, enabling joint inference and generation across modalities. This approach improves processing speed and reduces computational consumption, achieving a first token generation latency of only 111 milliseconds, far lower than existing models, allowing Ichigo to provide a near real-time voice interaction experience.
Ichigod's main functions
- Real-time speech processingIchigo processes voice input in real time, converting it into discrete tokens for rapid response.
- Cross-modal interactionIt supports interleaved sequence processing of voice and text, enabling true cross-modal interaction.
- Multi-turn dialogue managementMaintain contextual understanding in multi-turn conversations to provide accurate and personalized responses.
- Fuzzy input processingWhen faced with unclear voice input or background noise, ask the user to repeat, ensuring the accuracy of the interaction.
- Multilingual supportThanks to the pre-training of multilingual speech recognition datasets, Ichigo supports the processing of multiple languages.
Ichigo's technical principles
- Early fusion of mixed modesIchigo is based on early fusion technology, which merges voice and text data during the input stage to improve efficiency.
- Unified converter architectureIt uses a unified transformer architecture to process quantized speech and text tokens, supporting cross-modal learning and feature sharing.
- Voice to token conversionWhisperVQ technology is used to convert continuous speech signals into discrete tokens for model processing.
- Low-latency real-time performanceThe average latency for generating the first token is only 111 milliseconds, providing excellent real-time processing capabilities.
- Multilingual pre-trainingDuring the pre-training phase, a multilingual speech recognition dataset is used to enable the model to process multiple languages.
