摘要： The intelligibility of speech signals is improved in the many situations where a voice signal is communicated or stored. Means and methods are disclosed for developing a scheme with high voice signal intelligibility without sacrifice of voice quality. The disclosed method comprises certain steps, including, but not limited to: Learning the noise on near-end side and enhancing the far-end voice as a function of the noise level on the near-end side. The disclosed method and apparatus are especially useful to increase the intelligibility of the cell phone's loudspeaker output. The invention includes the processing of an input speech signal to generate an enhanced intelligent signal. In frequency domain, the FFT spectrum of the speech received from the far-end is modified in accordance with the LPC spectrum of the local background noise to generate an enhanced intelligent signal. In time domain, the speech is modified in accordance with the LPC coefficients of the noise to generate an enhanced intelligent signal.

摘要： VoIP phones according to the present invention include a microphone, which may be internal or external, and allow the user to communicate unobtrusively, check voice mail and conduct other activities in an environment which can be noisy in general and extremely noisy sometimes. Speech recognition functionally may also be used to generate and send touch tone or DTMF tones such as in response to call trees or voice recognition functionality used by airlines, credit card companies, voice mail systems, and other applications. A system and method of audio processing which provides enhanced speech recognition is provided. Audio input is received at the microphone which is processed by adaptive noise cancellation to generate an enhanced audio signal. The operation of the speech recognition engine and the adaptive noise canceller may be advantageously controlled based on Voice Activity Detection (VAD).
摘要翻译：根据本发明的VoIP电话包括麦克风，其可以是内部的或外部的，并且允许用户不引人注意地进行通信，检查语音邮件，并且在一般噪声和极其嘈杂的环境中进行其他活动。语音识别功能还可以用于生成和发送触摸音或DTMF音调，例如响应于航空公司，信用卡公司，语音邮件系统和其他应用使用的呼叫树或语音识别功能。提供了一种提供增强语音识别的音频处理系统和方法。在麦克风处接收音频输入，其通过自适应噪声消除处理以产生增强的音频信号。可以基于语音活动检测（VAD）来有利地控制语音识别引擎和自适应噪声消除器的操作。
