Audio quality feedback during live transmission from a source

A method is carried out by feedback system 131 for audio quality feedback during live transmission from a source 101 that is received at multiple audience devices 111-115. It comprises: obtaining 332 audio information of an audio signal, such as audio quality level, as received by at least some of the audience devices in a transmission session; classifying 333 one or more subsets of the audience devices by one or more common factors per subset; analyzing 334 the obtained audio information from the audience devices in conjunction with the classifications of the subsets of the audience devices to determine one or more common factors that affect received audio quality at an identified subset of the audience devices classified by the common factors; and providing feedback 335 of the common factors to at least one audience device in the identified subset or to the source device. The audio quality level may be evaluated by converting the audio signal using a voice-to-text conversion process, and determining a ratio of converted words to gaps in a sample period of the audio signal. The feedback may be used during teleconferencing to enable audience or source devices to take remedial action.
