This difference would be even larger for a longer recording. In this case, the latest version of DeepSpeech provides the transcription 260ms after the end of the audio, which is 73% faster than before the streaming decoder was implemented. Then, the distance from the end of the audio signal to the dotted line represents how long a user must wait after they’ve stopped speaking until the final transcript is computed and the application is able to respond. The dotted black line marks when the program has received the final transcription. The program requests an intermediate transcription roughly every second while the audio is being transcribed. In the following diagram, you can see the same audio file being processed in real time by DeepSpeech, before and after the decoder optimizations.

With both systems now capable of streaming, there’s no longer any need for carefully tuned silence detection algorithms in applications. In a previous blog post, I discussed how we made the acoustic model streamable. The decoder uses a beam search algorithm to transform the character probabilities into textual transcripts that are then returned by the system. The acoustic model is a deep neural network that receives audio features as inputs, and outputs character probabilities. Application developers can obtain partial transcripts without worrying about big latency spikes.ĭeepSpeech is composed of two main subsystems: an acoustic model and a decoder. Our new streaming decoder offers the largest improvement, which means DeepSpeech now offers consistent low latency and memory utilization, regardless of the length of the audio being transcribed. Consistent low latencyĭeepSpeech v0.6 includes a host of performance optimizations, designed to make it easier for application developers to use the engine without having to fine tune their systems. In this overview, we’ll show how DeepSpeech can transform your applications by enabling client-side, low-latency, and privacy-preserving speech recognition capabilities. Our latest release, version v0.6, offers the highest quality, most feature-packed model so far.

We also provide pre-trained English models. DeepSpeech is a deep learning-based ASR engine with a simple API.

The Machine Learning team at Mozilla continues work on DeepSpeech, an automatic speech recognition (ASR) engine which aims to make speech recognition technology and trained models openly available to developers.
