Abstract: In relation to telephone sets connected together over a radio channel, to enable a telephone set of a calling party to readily identify whether or not a call acknowledgement from a receiving party has been detected. After a call has been originated by way of a keyboard 22 of a radio telephone set, a call acknowledgement signal detection section 17c monitors a call acknowledgement signal transmitted from the calling party by way of a base station 30. When the call acknowledgement signal detection section 17c detects the call acknowledgement signal transmitted from the receiving party, a specific call acknowledgement sound signal is output from an audio output section 21. Further, a specific screen color is displayed on a display section 20.

Abstract: A vocal training apparatus accomplishes reproduction of a music signal recorded on an information medium, where the music signal includes a model vocal signal and an accompaniment signal. A model vocal signal is extracted from the music signal and a singer's vocal signal is received. The model vocal characteristics are measured from the model vocal signal and the singer's vocal characteristics are measured from the singer's vocal signal. The singer's vocal characteristics and the model vocal characteristics can then be compared to evaluate the singer's vocal characteristics relative to the model vocal characteristics.

Abstract: A music training apparatus performs a two-part reproduction including first and second parts, in which the first part is like a trial part which allows a video signal to be reproduced on a display unit but prohibits a sound signal to be generated from a speaker. The second part is like a formal part which allows an ordinary reproduction of both the video and sound signals. In the first part, a first pitch detector detects a pitch of a model singing signal memorized in a recording medium. Meanwhile, a second pitch detector detects a pitch of user's singing signal inputted from a microphone. If the pitches detected by the first and second pitch detectors are different from each other, an interval adjusting device changes the key so as to be in perfect pitch with each other before terminating the first part.
