Lyra 1.3.0 is now available. This release increases the speed and reduces the storage space of the model. We recommend all users upgrade if they do not need to reuse the earlier versions’ bitstream.
New Features
- The new model is 43% smaller (TFLite model size) and 20% faster (comparing 1.2.0 to 1.3.0 on Pixel 6 Pro). This is accomplished by storing some weights and performing arithmetic operations in 8-bit integers instead of 32-bit floats. Thanks to quantization aware training, the audio quality for the smaller and faster model remains as good as the previous model – our listening tests show that users have no preference for either this or the previous model. The bitstream, however, is different from the previous model due to the changed weights.
Breaking Changes
- The 1.3.0 bitstream is incompatible with 1.2.0.
