  2. Perceptual Evaluation of Audio Quality - Wikipedia

    en.wikipedia.org/wiki/Perceptual_Evaluation_of...

    Perceptual Evaluation of Audio Quality (PEAQ) is a standardized algorithm for objectively measuring perceived audio quality, developed in 1994–1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union's Radiocommunication Sector . It was originally released as ITU-R Recommendation BS.1387 in 1998 and ...

  3. Perceptual Objective Listening Quality Analysis - Wikipedia

    en.wikipedia.org/wiki/Perceptual_Objective...

    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.

  4. Perceptual Evaluation of Speech Quality - Wikipedia

    en.wikipedia.org/wiki/Perceptual_Evaluation_of...

    Perceptual Evaluation of Speech Quality (PESQ) is a family of standards comprising a test methodology for automated assessment of the speech quality as experienced by a user of a telephony system. It was standardized as Recommendation ITU-T P.862 [1] in 2001. PESQ is used for objective voice quality testing by phone manufacturers, network ...

  6. Psychoacoustics - Wikipedia

    en.wikipedia.org/wiki/Psychoacoustics

    Perceptual audio coding uses psychoacoustics-based algorithms. The psychoacoustic model provides for high quality lossy signal compression by describing which parts of a given digital audio signal can be removed (or aggressively compressed) safely—that is, without significant losses in the (consciously) perceived quality of the sound.

  7. Sound quality - Wikipedia

    en.wikipedia.org/wiki/Sound_quality

    Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...

  8. Signal strength and readability report - Wikipedia

    en.wikipedia.org/wiki/Signal_strength_and...

    A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report ...

  9. Harvard sentences - Wikipedia

    en.wikipedia.org/wiki/Harvard_sentences

    IEEE Recommended Practice for Speech Quality Measurements [3] sets out seventy-two lists of ten phrases each, described as the "1965 Revised List of Phonetically Balanced Sentences (Harvard Sentences)." They are widely used in research on telecommunications, speech, and acoustics, where standardized and repeatable sequences of speech are needed.
