This binary exposes a local gRPC interface that other services on the device can talk to, making it easy for multiple services to access speech recognition or speech synthesis as they need to, without additional libraries or integration.Įach model is only a couple hundred megabytes in size.

Each system (STT and TTS) provides customers with a binary, built for their specific hardware, operating system, and software environment. Speech On-Device is easy for developers to get started with. Speech On-Device TTS not only provides acoustic quality comparable to our WaveNet technology, DeepMind’s breakthrough model for generating more natural-sounding speech, but it also is significantly less computationally demanding and can easily run on embedded CPUs without the need for accelerators. These advancements have resulted in quality comparable to that of a server, while still allowing for models that are lightweight enough to run on local devices CPUs.įor Text-to-Speech, we leverage new technology developed at Google to bring high-quality voice into vehicles. Running locally is made possible by new modeling techniques, on both the Speech-to-Text (STT) and Text-to-Speech (TTS) fronts.įor Speech-to-Text (or ASR), years of work on our end-to-end Speech models, such as our latest conformer models, has decreased the size and compute necessary to run fully-featured speech models. Build speech experiences with–or without–network connectivityįrom cars that drive through tunnels, to apps running on integrated devices like kiosks, to IoT devices, Speech On-Device delivers server-quality voice capabilities with a fraction of the processing power-all while helping to maintain privacy by keeping data on the local device. These on-device Speech-to-Text and Text-to-Speech technologies have already been used in Google Assistant, but with Speech On-Device, a new generation of apps and services can harness this technology. With Speech On-Device, which went into GA at Google Cloud Next ‘22, we’re excited to embed the powerful speech recognition available in the cloud for a variety of new use cases in environments with inconsistent, little, or no internet connectivity. Typically, however, to successfully provide high-quality speech results to consumers, the AI systems responsible for ASR have needed a stable cloud connection to specialized hardware.
With our Speech-to-Text (STT) API now processing over 1 billion minutes of speech each month, it’s clear that voice assistants - and Automatic Voice Recognition (ASR) in general - are essential to how millions of people make decisions and navigate their lives. Maybe it’s a network outage, or maybe you’re in the middle of nowhere, far away from coverage-either way the result is the same: the voice assistant can’t connect to the server and thus cannot help. We’ve all been there- asking a voice assistant to play a song, launch an app, or answer a question, but the assistant doesn’t comply.
