Dynamically providing to a person feedback pertaining to utterances spoken or sung by the person

A method, comprising:

• detecting, in real time, by a mobile communication device, utterances spoken or sung by a first person when the utterances are spoken or sung;
• comparing, in real time using a processor of the mobile communication device, the detected utterances spoken or sung by the first person to at least a stored sample of utterances spoken or sung by the first person;
• based on the comparing the detected utterances spoken or sung by the first person to at least the stored sample of utterances spoken or sung by the first person, isolating audio of the utterances spoken or sung by the first person from a background noise;
• determining a volume of the utterances spoken or sung by the first person relative to the background noise;
• generating, by the mobile communication device, a key indicator that indicates the volume of the detected utterances spoken or sung by the first person relative to the background noise;
• and
• based on the key indicator, communicating, by the mobile communication device, information indicating the volume of the detected utterances spoken or sung by the first person relative to the background noise.

A mobile communication device, comprising:

• a processor programmed to initiate executable operations comprising:
• detecting, in real time, utterances spoken or sung by a first person when the utterances are spoken or sung;
• comparing, in real time, the detected utterances spoken or sung by the first person to at least a stored sample of utterances spoken or sung by the first person;
• based on the comparing the detected utterances spoken or sung by the first person to at least the stored sample of utterances spoken or sung by the first person, isolating audio of the utterances spoken or sung by the first person from a background noise;
• determining a volume of the utterances spoken or sung by the first person relative to the background noise;
• generating a key indicator that indicates the volume of the detected utterances spoken or sung by the first person relative to the background noise;
• and
• based on the key indicator, communicating information indicating the volume of the detected utterances spoken or sung by the first person relative to the background noise.

A computer program product comprising a computer readable storage medium having program code stored thereon, the program code executable by a processor to perform a method comprising:

• detecting, in real time, utterances spoken or sung by a first person when the utterances are spoken or sung;
• comparing, by the processor and in real time, the detected utterances spoken or sung by the first person to at least a stored sample of utterances spoken or sung by the first person;
• based on the comparing the detected utterances spoken or sung by the first person to at least the stored sample of utterances spoken or sung by the first person, isolating audio of the utterances spoken or sung by the first person from a background noise;
• determining a volume of the utterances spoken or sung by the first person relative to the background noise;
• generating a key indicator that indicates the volume of the detected utterances spoken or sung by the first person relative to the background noise;
• and
• based on the key indicator, communicating information indicating the volume of the detected utterances spoken or sung by the first person relative to the background noise.
