1. A communication apparatus mounted with a speech speed conversion device, comprising:

  • an encoder that compresses telephone call voice data which is transmitted from another communication apparatus;

    a message preserver that preserves the telephone call voice data, which is compressed by the encoder, as a message;

    a decoder that expands the telephone call voice data which is preserved by the message preserver;

    a speech speed convertor that includes a voice data buffer which temporarily maintains the telephone call voice data expanded by the decoder, and that performs speech speed conversion on the telephone call voice data which is read from the voice data buffer, and outputs resulting voice from a speaker; and

    a monitor that temporarily stops to expand reading of the telephone call voice data by the decoder in a case where the monitor determines that an idle capacity of the voice data buffer becomes less than a predetermined lower limit value,wherein the speech speed convertor continues to perform speech speed conversion on the telephone call voice data that is already read by the decoder and stored in the voice data buffer, and outputs the resulting voice from the speaker while the monitor temporarily stops reading of the telephone call voice data by the decoder.
