Voice problems that require voice analysis most commonly originate from the vocal folds or the laryngeal musculature that controls them, since the folds are subject to collision forces with each vibratory cycle and to drying from the air being forced through the small gap between them, and the laryngeal musculature is intensely active during speech or singing and is subject to tiring.
P.OLQA was the working title of an ITU-T standard that covers a model to predict speech quality by means of analyzing digital speech signals. [1] The model was standardized as Recommendation ITU-T P.863 (Perceptual objective listening quality assessment) in 2011.
Subvocalization, or silent speech, is the internal speech typically made when reading; it provides the sound of the word as it is read. [1] [2] This is a natural process when reading, and it helps the mind to access meanings to comprehend and remember what is read, potentially reducing cognitive load.
Active voice is a grammatical voice prevalent in many of the world's languages. It is the default voice for clauses that feature a transitive verb in nominative–accusative languages, including English and most Indo-European languages. In these languages, a verb is typically in the active voice when the subject of the verb is the doer of the ...
The content analysis is the central part of the digital forensic analysis process and it is based on the content of the audio file to find traces of manipulation and anti-forensic processing operations. The content-based audio forensic techniques can be split in the following categories: Electrical Network Frequency (ENF)
Voice activity detection (VAD), also known as speech activity detection or speech detection, is the detection of the presence or absence of human speech, used in speech processing. [1] The main uses of VAD are in speaker diarization , speech coding and speech recognition . [ 2 ]
Voice stress analysis (VSA) and computer voice stress analysis (CVSA) are collectively a pseudoscientific technology that aims to infer deception from stress measured in the voice. The CVSA records the human voice using a microphone, and the technology is based on the tenet that the non-verbal, low-frequency content of the voice conveys ...
The evidence collected can correspond to plain data or, with the broad usage of Voice-over-IP (VoIP) technologies, especially over wireless, can include voice conversations. Analysis of wireless network traffic is similar to that on wired networks, however there may be the added consideration of wireless security measures .
