spoken dialog system
支持用户以口语进行人机对话的系统，通常包含自动语音识别 (ASR)、自然语言理解、对话管理和语音合成等模块。Siri、Alexa、客服机器人等都是典型实例。
English Definition
"A computer system that enables spoken-language interaction with users, typically combining automatic speech recognition (ASR), natural language understanding, dialog management, and speech synthesis."
用法说明 · 针对中文母语者
学术文献中比 'voice assistant' 更正式，常出现在 NLP/HCI 论文标题中。口语对话系统与纯语音识别 (speech recognition) 不等价——后者只把声音转为文字。
常见错误
- ·与 'speech recognition' 混用——后者是前者的子模块
- ·认为只要有 ASR 就是 spoken dialog system——还需要对话管理层
