The mobile market is an interesting and rapidly growing market. Although new features are coming up, speech transmission is still one of the most important applications. This contribution addresses frequently asked questions concerning speech quality of mobile phones. The analyses discussed in this contribution focus purely on the speech quality and the capability of today’s signal processing. All other aspects such as cost factors or different customer groups being addressed by a specific type of phone are disregarded. Extracted from a huge amount of data some implementation examples are analyzed. The paper discusses the typical range of single parameters. The intention of this paper is to provide useful information for manufacturers and operators for development and comparison. The analyses are based on the three latest phones on the market of 9 different competitive mobile manufacturers.
