Abstract

The applications of speech interfaces, commonly used for search and personal assistants, are diversifying to include wearables, appliances, and robots. Hardware-accelerated automatic speech recognition (ASR) is needed for scenarios that are constrained by power, system complexity, or latency. Furthermore, a wakeup mechanism, such as voice activity detection (VAD), is needed to power gate the ASR and downstream system. This paper describes IC designs for ASR and VAD that improve on the accuracy, programmability, and scalability of previous work.

14.4具有深度神经网络声学模型和声控功率门控的可扩展语音识别器
通常用于搜索和个人助理的语音界面的应用正在多样化,包括可穿戴设备、家电和机器人。对于受功率、系统复杂性或延迟限制的场景,需要硬件加速的自动语音识别(ASR)。此外,需要一个唤醒机制,如语音活动检测(VAD),为ASR和下游系统供电。本文介绍了ASR和VAD的IC设计,这些设计提高了以前工作的准确性、可编程性和可扩展性。
