Stop consonant without a release burst

A stop with no audible release, also known as an unreleased stop or an applosive, is a stop consonant with no release burst: no audible indication of the end of its occlusion (hold). In the International Phonetic Alphabet, lack of an audible release is denoted with an upper right corner diacritic after the consonant letter, as in: , ,
Audibly released stops, on the other hand, are not normally indicated. If a final stop is aspirated, the aspiration diacritic is sufficient to indicate the release. Otherwise, the "unaspirated" diacritic of the Extended IPA may be employed for this: apt .

In most dialects of English, the first stop of a cluster has no audible release, as in apt , doctor , or logged on Although such sounds are frequently described as "unreleased", the reality is that since the two consonants overlap, the release of the former takes place during the hold of the latter, masking the former's release and making it inaudible. That can lead to cross articulations that seem very much like deletions or complete assimilation. For example, hundred pounds may sound like but X ray and electropalatographic studies demonstrate that since inaudible and possibly weakened contacts may still be made, the second in hundred pounds does not entirely assimilate a labial place of articulation but co occurs with it. In American English, a word final stop is typically unreleased; that is especially the case for /t/, but in that position, it is also analyzed as experiencing glottal reinforcement. Such sounds may occur between vowels, as in some pronunciations of out a lot. The overlap there appears to be with a glottal stop, : the is pronounced, and since it is between vowels, it must be released. However, its release is masked by the glottal stop. (See: T glottalization, in some dialects). The term "unreleased" is also used for a stop before a homorganic nasal, as in catnip. In such cases, however, the stop is released as a nasal in a nasal release and so it would be more precisely transcribed .

In most languages in East and Southeast Asia with final stops, such as Cantonese, Hokkien, Korean, Malay, Thai, and West Coast Bajau, the stops are not audibly released: mak That is true even between vowels. That is thought to be caused by an overlapping glottal stop)

In Pirahã, the only surviving dialect of the Mura language, there is a special register of speech using solely humming, which does not involve an audible release and may be transcribed as of different length and tone.
