Glottal stop does not have the status of a phoneme in Czech, but it can have a significant perceptual impact. Although it does not distinguish the meaning of words, its use contributes to higher intelligibility of speech.
It is one of the sound phenomena by which the speech of native and non-native speakers can differ; glottalization in the Czech speech of non-native speakers compared to native ones is the subject of this study. Recordings of the read text with a length of 216 words, which contains 29 positions with the potential occurrence of glottal stop, divided into 4 types, were analysed.
The respondents were native speakers (females) of Russian (12 people), Ukrainian (9), and Czech (13).
