Pronunciation assessment
open-in-new
<p>Automatic pronunciation assessment is the use of <a href="/facts/Speech_recognition/z7S7Pgk6">speech recognition</a> to verify the correctness of pronounced <a href="/facts/Speech/WEelhfTs">speech</a>, as distinguished from manual assessment by an instructor or proctor. Also called speech verification, pronunciation evaluation, and pronunciation scoring, the main application of this technology is computer-aided pronunciation teaching (CAPT) when combined with <a href="/facts/Computer-aided_instruction/5lf2A2Vj">computer-aided instruction</a> for <a href="/facts/Computer-assisted_language_learning/Hm30fEyI">computer-assisted language learning</a> (CALL), speech <a href="/facts/Remedial_education/UBwtS0NY">remediation</a>, or <a href="/facts/Accent_reduction/9z6z8uwY">accent reduction</a>. </p><p>Pronunciation assessment does not determine unknown speech (as in <a href="/facts/Digital_dictation/9Sk80e6C">dictation</a> or <a href="/facts/Automatic_transcription/xDpss3D1">automatic transcription</a>) but instead, knowing the expected word(s) in advance, it attempts to verify the correctness of the learner's <a href="/facts/Pronunciation/zqdlUoDU">pronunciation</a> and ideally their <a href="/facts/Intelligibility_(communication)/PVwX3CP9">intelligibility</a> to listeners, sometimes along with often inconsequential <a href="/facts/Prosody_(linguistics)/UDzAIz46">prosody</a> such as <a href="/facts/Intonation_(linguistics)/yzNJ9gdA">intonation</a>, <a href="/facts/Pitch_(music)/fQAK0JsC">pitch</a>, <a href="/facts/Speech_tempo/xPonKmoP">tempo</a>, <a href="/facts/Isochrony/VtL0NAul">rhythm</a>, and syllable and word <a href="/facts/Vocal_stress/rsHpCK5H">stress</a>. Pronunciation assessment is also used in <a href="/facts/Reading_tutoring/zmYVXRKf">reading tutoring</a>, for example in products such as <a href="/facts/Microsoft_Teams/w21lo6BU">Microsoft Teams</a> and from Amira Learning. Automatic pronunciation assessment can also be used to help diagnose and treat <a href="/facts/Speech_disorders/99psJAz4">speech disorders</a> such as <a href="/facts/Speech_apraxia/VdN8G6hp">apraxia</a>. </p>
