Conversation analysis (CA) is an approach to the study of social interaction that investigates the methods members use to achieve mutual understanding through the transcription of naturally occurring conversations from audio or video. [1] It focuses on both verbal and non-verbal conduct, especially in situations of everyday life.
Audio analysis refers to the extraction of information and meaning from audio signals for analysis, classification, storage, retrieval, synthesis, etc.The observation mediums and interpretation methods vary, as audio analysis can refer to the human ear and how people interpret the audible sound source, or it could refer to using technology such as an audio analyzer to evaluate other qualities ...
Example of audio description with Steamboat Willie. Audio description (AD), also referred to as a video description, described video, or visual description, is a form of narration used to provide information surrounding key visual elements in a media work (such as a film or television program, or theatrical performance) for the benefit of blind and visually impaired consumers.
Content analysis is the study of documents and communication artifacts, which might be texts of various formats, pictures, audio or video. Social scientists use content analysis to examine patterns in communication in a replicable and systematic manner. [ 1 ]
The possibility of performing forensic audio analysis depends on the availability of audio recordings made outside the boundaries of a recording studio. The first portable magnetic tape recorders appeared in the 1950s and soon these devices were used to obtain clandestine recordings of interviews and wiretaps, as well as to record ...
Speech coding is an application of data compression to digital audio signals containing speech.Speech coding uses speech-specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression algorithms to represent the resulting modeled parameters in a compact bitstream.
In speech communication, intelligibility is a measure of how comprehensible speech is in given conditions. Intelligibility is affected by the level (loud but not too loud) and quality of the speech signal, the type and level of background noise, reverberation (some reflections but not too many), and, for speech over communication devices, the properties of the communication system.
Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in ...
