Moonshine Tiny
Model Overview
Moonshine is a high-efficiency automatic speech recognition (ASR) model designed specifically for real-time speech recognition. Unlike Whisper, which processes audio in fixed 30-second chunks, Moonshine uses a variable-length architecture that only computes the actual duration of the speech received.
Useful Sensors developed Moonshine and released the English model as open-source. There are 2 models of different sizes and capabilities - base and tiny. The tiny version utilizes 27M parameters.
Model Features
- Model Type: Automatic Speech Recognition
- Input: Raw waveform (1D array of floats) 16kHz mono audio up to 30 seconds
- Output: Sequence of token IDs (integers)
- Quantization: None
Recommended Platforms
- Synaptics Astra™ SL2600-Series with Torq
- Synaptics Astra™ SL1600-Series with Synap
