This study focuses on the production and perception of English words with a fortis vs. lenis obstruent in the syllable coda. The contrast is mostly cued by the duration of the preceding vowel, which is shorter before fortis than before lenis sounds in native speech. In the first experiment we analyzed the production of 10 Czech speakers of English and compared them to two native controls. The results showed that the Czech speakers did not sufficiently exploit duration to cue the identity of the word-final obstruent. In the second experiment we manipulated C and V durations in target words to transplant the native ratios onto the Czech-accented speech, enhancing the fortis–lenis contrast, and vice versa. 108 listeners took part in a word-monitoring task in which reaction times were measured. The hypothesized advantage to items in which the target word (with a fortis or lenis obstruent) was semantically congruent with the following context was not confirmed, and subsequent analyses showed that the words’ frequency of use and the collocations they enter into strongly affect speech processing and correlate to a large degree with the reaction times.

This study focuses on voicing assimilation across word boundaries in the speech of second language (L2) users. We compare native speakers of British English to speakers of two West Slavic languages, Czech and Slovak, which, despite their many similarities, differ with respect to voicing assimilation rules. Word-final voicing was analysed in 30 speakers, using the static value of voicing percentage and the voicing profile method. The results of linear mixed-effects modelling suggest an effect of first language (L1) transfer in all L2 English speaker groups, with the tendency to assimilate being correlated with the strength of foreign accent. Importantly, the two language groups differed in assimilation strategies before sonorant consonants, as a clear effect of L1-based phonetic influence.

Pauses act as important acoustic cues to prosodic phrase boundaries. However, the distribution and phonetic characteristics of pauses have not yet been fully described either cross-linguistically or in different genres and speech styles within languages. The current study examines the pausal performance of 24 Czech speakers in two genres of read speech: news reading and poetry reciting. The pause rate and pause duration are related to genre differences, overt and covert text organization, and speech tempo. We found a significant effect of several levels of text organization, including a strong effect of punctuation. This was reflected in both measures of pausal performance. A grammatically informed analysis of a subset of pauses within the smallest units revealed a significant contribution for pause rate only. An effect of tempo was found in poetry reciting at a macro level (speaker averages) but not when pauses were observed individually. Genre differences did not manifest consistently and analogically for the two measures. The findings provide evidence that pausing is used systematically by speakers in read speech to convey not only prosodic phrasing but also text structure, among other things.

The use of linking or glottalization contributes to the characteristic sound pattern of a language, and the use of one in place of the other may affect a speaker’s comprehensibility and fluency in certain contexts. In this study, native speakers of Czech, a language that is associated with a frequent use of glottalization in vowel-initial word onsets, are examined in the second language (L2) context of three Romance languages that predominantly employ linking between words (Spanish, Italian and Portuguese). In total, 29 native speakers and 51 non-native learners were asked to read a short text in the respective language. The learners were divided into two groups based on their experience with the target language. A number of other factors were examined in a mixed-effects logistic regression model (segmental context, lexical stress, prosodic breaks, and the semantic status of the words). The main results show that, regardless of the target language, the more experienced (ME) learners displayed significantly lower rates of glottalization than the less experienced (LE) learners, but significantly higher rates than native speakers. The pedagogical implications of the results are discussed.

Czech and English are languages which differ with respect to the implementation of voicing. Unlike in English, there is a considerable agreement between phonological (systemic) and phonetic (actual) voicing in Czech, and, more importantly, the two languages have different strategies for the assimilation of voicing across the word boundary. The present study investigates the voicing in word-final obstruents in Czech speakers of English with the specific aim of ascertaining whether the degree of the speakers’ foreign accent correlates with the way they treat English obstruents in assimilatory contexts. L2 speakers, divided into three groups of varying accentedness, were examined employing categorization and a voicing profile method for establishing the presence/absence of voicing. The results suggest that speakers with a different degree of Czech accent do differ in their realization of voicing in the way predicted by a negative transfer of assimilatory habits from Czech.

The study investigates the attitudes of 254 Czech students towards English as the main language taught at secondary schools. The questionnaire enquired about their perspectives on learning English in general, British and American cultures and accents of English. Such preferences may have implications for pronunciation model selection in TEFL. In addition, the participants evaluated 12 words pronounced in British or American English for pleasantness, and also assigned them to one of the varieties. Despite the predominance of American culture and despite equal distribution of cultural preferences and equal aesthetic evaluation of the accents, the British variety was marked as more prestigious and was also identified more successfully. Interestingly, the findings differed between students from the capital city and those from regional schools.
