A transmitting apparatus, a transmitting method, a receiving apparatus, a receiving method, a transceiver, a communication apparatus and method, a recording medium, and a program in which high quality voice can be decoded. A cellular telephone outputs coded voice data and also supplies uncoded voice sample data to a switching center while a telephone call is not made. Based on voice data used for the previous calculation processing and newly input voice data, the switching center performs calculation processing for quality-improving data for improving the quality of voice to be output from a cellular telephone that receives the coded voice data. The switching center stores the optimal quality-improving data as a user information database in association with the cellular telephone. The cellular telephone decodes the coded voice data based on the optimal quality-improving data supplied from the switching center.
