摘要： A mobile telephone system and a method for answering a mobile telephone incoming call by a user's verbal command, to allow hands-free voice. The mobile telephone system includes a carkit and a mobile telephone. The mobile telephone has a programming key for pre-programming the user's voice greeting, a keypad for answering the call in telephone mode, a microphone for entering a user's verbal command for answering the call in carkit mode, a digital processor connected to the microphone for performing spectrum analysis and feature extractions of the user's verbal command in carkit mode, and a memory connected to the digital processor, having a database for storing the user's pre-programmed voice greeting digitized speech pattern. The pre-programmed voice greeting may be a factory-programmed voice greeting or the user's pre-programmed voice greeting, if previously initialized after pressing the programming key. The digital processor performs spectrum analysis and feature extractions of the user's verbal command for determining if a match exists between the user's verbal command and the stored user pre-programmed voice greetings. The digital processor also checks whether the user's verbal command reaches a pre-programmed pass/fail voice threshold level, if a match is confirmed.

摘要： An echo canceller includes an initial delay estimator producing a reference signal containing an identified frequency component masked by means of frequency masking effect to output the reference signal on an echo path, and detecting, from a sending voice signal, an echo component of the identified frequency component derived from the reference signal. The estimator finds an initial delay amount on the echo path on the basis of a forming timing of the reference signal containing the identified frequency component and a detection timing of the echo component in the identified frequency component in the sending voice signal. The echo canceller includes a delay circuit for delaying a received voice signal by the initial delay amount on the echo path obtained from the estimator to supply a resulting signal to a pseudo echo generator.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a call is disabled in the case of phone book function activation and a phone book cannot be retrieved in contact with an opposite party of an inquiry source in a conventional technology in which a telephone number retrieved by operating the phone book during the call, is voice-converted and informed to the opposite party. SOLUTION: A telephone device comprises: in-call phone book function activation means starting a phone book function during a call; and hand-free-call switch means switching the call to a hand-free call during the call. When a predetermined specific operation is conducted during the call, the phone book function is started in a state that the call is maintained while the call is switched automatically to the hand-free call.

摘要： PROBLEM TO BE SOLVED: To provide a voice communication device which does not degrade communication quality even if a residual echo suppression function overworks. SOLUTION: The voice communication device includes an echo canceller which is composed of an echo canceller body that generates a quasi-echo to remove echo components included in transmission signals, and a residual echo component suppression means for suppressing residual echo components included in transmission signals that are output from the echo canceller body. In addition, the voice communication device includes a background noise component extraction means for extracting background noise components from transmission signals, and a noise superimposition means for superimposing the extracted background noise components on transmission signals that are output from the echo canceller.
