Speech to text ai open source11/18/2023 ![]() Robust to brief network loss (when traveling and switching between network and Wi-Fi).Google lists the following features for the speech engine (speaker identification is not included): The encoder increases bitrate just enough so that “latency is visually indistinguishable to sending uncompressed audio.” Live Transcribe speech engine features To reduce latency even further than the Cloud Speech API already does, Live Transcribe uses a custom Opus encoder. Overall, the team was able to achieve “a 10 times reduction in data usage without compromising accuracy.” Google also uses speech detection to close the network connection during extended periods of silence. Opus, meanwhile, allows data rates many times lower than most music streaming services while still preserving the important details of the audio signal. AMR-WB saves a lot of data but is less accurate in noisy environments. FLAC (a lossless codec) preserves accuracy, doesn’t save much data, and has noticeable codec latency. To reduce bandwidth requirements and costs, Google also evaluated different audio codecs: FLAC, AMR-WB, and Opus. (When Live Caption arrives later this year, it will only work on select Android Q devices.) The other main difference: Live Transcribe is available on 1.8 billion Android devices. You can also type back into it - Live Transcribe is really a communication tool. ![]() Live Transcribe can caption real-time spoken words in over 70 languages and dialects. ![]() Unlike Android’s upcoming Live Caption feature, Live Transcribe is a full-screen experience, uses your smartphone’s microphone (or an external microphone), and relies on the Google Cloud Speech API. The tool uses machine learning algorithms to turn audio into real-time captions. Google released Live Transcribe in February. The source code is available now on GitHub. The company hopes doing so will let any developer deliver captions for long-form conversations. Google today open-sourced the speech engine that powers its Android speech recognition transcription tool Live Transcribe. At the event, we will also announce 25 top game startups as the 2024 Game Changers. We're thrilled to announce the return of GamesBeat Next, hosted in San Francisco this October, where we will explore the theme of "Playing the Edge."
