Snips Voice Platform: an embedded Spoken Language Understanding system for private-by-design voice interfaces
Table 4: Comparison of speed and memory performance of nnet-256 and nnet-768. RTF refers to real time ratio.
['[BOLD] Model', '[BOLD] Num. Params (M)', '[BOLD] Size (MB)', '[BOLD] RTF (Raspberry Pi 3)']
The gain is similar in RAM. In terms of speed, the nnet-256 is 6 to 10 times faster than the nnet-768. These tradeoffs and comparison with other trained models led us to select the nnet-256. It has a reasonable speed and memory footprint, and the loss in accuracy is compensated by the adapted LM and robust NLU.
