Abstract: A voice control device has a speech command recognizer, a sensor data processor and a decision making circuit. The speech command recognizer is arranged for performing speech command recognition to output a recognized speech command. The sensor data processor is arranged for processing sensor data generated from at least one auxiliary sensor to generate a detection output. The decision making circuit is arranged for deciding a response of the voice control device according to the recognized speech command and the detection output. The same speech command is able to trigger difference responses according to the detection output (e.g., detected motion). Besides, an adaptive training process may be employed to improve the accuracy of the sensor data processor. Hence, the voice control device may have improved performance of the voice control feature due to a reduce occurrence probability of miss errors and false alarm errors.

Abstract translation: 语音控制装置具有语音指令识别器，传感器数据处理器和决策电路。 语音指令识别器被配置为执行语音命令识别以输出识别的语音命令。 传感器数据处理器被布置用于处理从至少一个辅助传感器生成的传感器数据以产生检测输出。 决定电路被配置为根据识别的语音命令和检测输出来决定语音控制装置的响应。 相同的语音命令能够根据检测输出（例如，检测到的运动）触发差异响应。 此外，可以采用自适应训练过程来提高传感器数据处理器的精度。 因此，语音控制装置可能由于错误错误和错误警报错误的发生概率的降低而具有改进的语音控制特征的性能。
