    en.wikipedia.org/wiki/Remote_Infrared_Audible...

    Remote infrared audible signage (RIAS) was developed by Smith-Kettlewell Eye Research Institute [1] (as Talking Signs R) [2] so that print-disabled people, such as those that are blind or have low-vision, or are illiterate, foreign, or visually impaired, would be able to access the same type of information available through textual print signs within the built environment.

  3. Temporal envelope and fine structure - Wikipedia

    en.wikipedia.org/wiki/Temporal_envelope_and_fine...

    Changes in the signal envelope can be measured using several different procedures. The presence of noise or reverberation will reduce the modulation depth of a signal, and multiband measurement of the envelope modulation depth of the system output is used in the speech transmission index (STI) to estimate intelligibility. [259]

  4. Intelligibility (communication) - Wikipedia

    en.wikipedia.org/wiki/Intelligibility...

    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.

  5. Switchboard Telephone Speech Corpus - Wikipedia

    en.wikipedia.org/wiki/Switchboard_Telephone...

    The Switchboard Telephone Speech Corpus is a corpus of spoken English language consisted of almost 260 hours of speech. It was created in 1990 by Texas Instruments via a DARPA grant, and released in 1992 by NIST. The corpus contains 2,400 telephone conversations among 543 US speakers (302 male, 241 female).

  6. 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 ...

  7. Acoustic phonetics - Wikipedia

    en.wikipedia.org/wiki/Acoustic_phonetics

    Acoustic phonetics is a subfield of phonetics, which deals with acoustic aspects of speech sounds. Acoustic phonetics investigates time domain features such as the mean squared amplitude of a waveform, its duration, its fundamental frequency, or frequency domain features such as the frequency spectrum, or even combined spectrotemporal features and the relationship of these properties to other ...

  8. Phases of speech - Wikipedia

    en.wikipedia.org/wiki/Phases_of_speech

    In a simple form of communication between two people, such as a short dialog, the speaker's utterance and transmission of speech sounds (or speech signal) to the hearer encompass seven phases of speech, namely: [1] neurolinguistic programming; neuromuscular phase; organic phase; aerodynamic phase; acoustic phase; neuroreceptive phase

  9. Speech transmission index - Wikipedia

    en.wikipedia.org/wiki/Speech_transmission_index

    Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal.
