Controlling mute function on telephone
A method for controlling a mute function in a telephone device, and the telephone device and a computer program product that implements the method. The method includes: while the mute function is active, voice recognition software in the telephone device processes sound detected by a microphone in the telephone device to recognize and identify one or more specific words as having been spoken by a specific person and not by another person, and in response, the telephone device activates an alarm in the telephone device to communicate that the mute function is active.
1. A method for controlling a mute function in a telephone device, the method comprising:
while the mute function is active, voice recognition software in the telephone device processing sound detected by a microphone in the telephone device;
ascertaining whether a magnitude of an analog signal representing the detected sound exceeds a predetermined threshold;
if said ascertaining ascertains that the magnitude does not exceed the predetermined threshold, then identifying the detected sound as being noise and not permitting an alarm in the telephone device to be activated; and
if said ascertaining ascertains that the magnitude exceeds the predetermined threshold, then determining whether one or more specific words have been spoken by a specific person and not by the another person, and if so then said telephone device activating the alarm, and if not then not permitting the alarm to be activated.
2. The method of claim 1 , wherein the voice recognition software was trained, prior to the sound having been detected, to differentiate the one or more specific words spoken by the specific person from the same one or more specific words spoken by other people.
3. The method of claim 1 , wherein the alarm is an audible sound.
4. A computer program product for controlling a mute function in a telephone device, the computer program product comprising a computer-readable storage device in the telephone device and program code stored on the storage device, wherein the program code comprises:
program instructions to process, by voice recognition software while the mute function is active, sound detected by a microphone in the telephone device;
program instructions to ascertain whether a magnitude of an analog signal representing the detected sound exceeds a predetermined threshold;
program instructions, if it is ascertained that the magnitude does not exceed the predetermined threshold, to identify the detected sound as being noise and not permit an alarm in the tele hone device to be activated; and
program instructions, if it is ascertained that the magnitude exceeds the predetermined threshold, to determine whether one or more specific words have been spoken by a specific person and not by the another person, and if so then to activate the alarm by the telephone device, and if not then to not permit the alarm to be activated.
5. The computer program product of claim 4 , wherein the voice recognition software was trained, prior to the sound having been detected, to differentiate the one or more specific words spoken by the specific person from the same one or more specific words spoken by other people.
6. The computer program product of claim 4 , wherein the alarm is an audible sound.
7. A telephone device, comprising: a mute function, a microphone for sensing sound reaching the telephone device, a processor, a memory, a computer-readable storage device and program code stored on the storage device for execution by the processor via the memory, wherein the program code comprises: program instructions to process, by voice recognition software while the mute function is active, sound detected by the microphone in the telephone device;
program instructions to ascertain whether a magnitude of an analog signal representing the detected sound exceeds a predetermined threshold;
program instructions, if it is ascertained that the magnitude does not exceed the predetermined threshold, to identify the detected sound as being noise and not permit an alarm in the telephone device to be activated; and
program instructions, if it is ascertained that the magnitude exceeds the predetermined threshold, to determine whether one or more specific words have been spoken by a specific person and not by the another person, and if so then to activate the alarm by the telephone device, and if not then to not permit the alarm to be activated.
8. The telephone device of claim 7 , wherein below the predetermined threshold, the detected sound is identified as being noise, as part of the identifying that the specific word is spoken by the specific person.
9. The telephone device of claim 7 , wherein the alarm is an audible sound.
