A method of providing an audio communication between three or more telecommunication devices whereby the audio communication enables a simultaneous, bi-directional exchange of audio data between the three or more telecommunication devices, the method comprising the steps of: associating the three or more telecommunication devices with the audio communication; determining, for the three or more telecommunication devices, parameter values of one or more parameters related to perspicuity, whereby the term perspicuity is meant to express the fact that audio data/signals, e.g. speakers' voices and other acoustic information, are perspicuous, i.e. clearly presented, in a bidirectional communication so that the audio data/signals can be easily understood, i.e. perceived, by listeners; grouping the three or more telecommunication devices into two or more speaker groups (CR11, CR12, CR13) dependent on the determined parameter values; on request from a telecommunication device of the three or more telecommunication devices, changing an association of the requesting telecommunication device with a first speaker group of the two or more speaker groups (CR11, CR12, CR13) to an association of the requesting telecommunication device with a second speaker group of the two or more speaker groups (CR11, CR12, CR13); when receiving audio data from a first telecommunication device of the three or more telecommunication devices, determining a relationship of the first telecommunication device with the two or more speaker groups (CR11, CR12, CR13); and processing the audio data received from the first telecommunication device and distributing the processed audio data to one or more telecommunication devices of the three or more telecommunication devices dependent on the determined relationship of the first telecommunication device and on the determined parameter values; the method being characterized by providing a perspicuity control for the audio communication by means of a decision to group speakers into speaker groups based on an understandability coefficient measurement comprising: number of interruptions per second, spectral perceptibility of single vowels and consonants, perceptibility of words or sentences, loudness ratio of foreground to background speakers. associating the three or more telecommunication devices with the audio communication; determining, for the three or more telecommunication devices, parameter values of one or more parameters related to perspicuity, whereby the term perspicuity is meant to express the fact that audio data/signals, e.g. speakers' voices and other acoustic information, are perspicuous, i.e. clearly presented, in a bidirectional communication so that the audio data/signals can be easily understood, i.e. perceived, by listeners; grouping the three or more telecommunication devices into two or more speaker groups (CR11, CR12, CR13) dependent on the determined parameter values; on request from a telecommunication device of the three or more telecommunication devices, changing an association of the requesting telecommunication device with a first speaker group of the two or more speaker groups (CR11, CR12, CR13) to an association of the requesting telecommunication device with a second speaker group of the two or more speaker groups (CR11, CR12, CR13); when receiving audio data from a first telecommunication device of the three or more telecommunication devices, determining a relationship of the first telecommunication device with the two or more speaker groups (CR11, CR12, CR13); and processing the audio data received from the first telecommunication device and distributing the processed audio data to one or more telecommunication devices of the three or more telecommunication devices dependent on the determined relationship of the first telecommunication device and on the determined parameter values; the method being characterized by providing a perspicuity control for the audio communication by means of a decision to group speakers into speaker groups based on an understandability coefficient measurement comprising: number of interruptions per second, spectral perceptibility of single vowels and consonants, perceptibility of words or sentences, loudness ratio of foreground to background speakers.
