Experimental version of LPCNet that has been used to develop FreeDV
|
|
2020 - a HF radio Digial Voice mode for over the air experimentation
|
|
with Neural Net speech coding. Possibly the first use of Neural Net
|
|
speech coding in real world operation.
|
|
|
|
From https://people.xiph.org/~jm/demo/lpcnet/ :
|
|
|
|
Work in progress software for researching low CPU complexity
|
|
algorithms for speech synthesis and compression by applying Linear
|
|
Prediction techniques to WaveRNN. High quality speech can be
|
|
synthesised on regular CPUs (around 3 GFLOP) with SIMD support (AVX,
|
|
AVX2/FMA, NEON currently supported). The code also supports very low
|
|
bitrate compression at 1.6 kb/s.
