Spanish/Catalan learners of English as a Foreign Language (EFL) attended a formal instruction (FI) period combined with explicit pronunciation instruction, which consisted of theoretical and practical approaches to English segmental phonetics as well as a contrastive analysis between the participants’ first languages and the target language, English. The EFL learners’ ability to perceive and produce L2 vowels was assessed before and after the 8-week instructional treatment. Results show that the EFL learners significantly improved their perception of vowel sounds embedded in real and non-words. However, no improvement in production was found as a result of the instruction received. While these results suggest that learners’ perceptual skills can be improved with teacher-led instruction, the quantity and availability of explicit pronunciation instruction is not sufficient to modify learners’ speech production. Thus, optimal results require learners to continue learning outside the classroom context. With this aim, this paper presents two autonomous activities developed to increase learners’ awareness about phonology: L1-L2 Pronunciation Comparison Task and a Phonological Self-awareness Questionnaire.

Following the Covid-19 pandemic, digital technology is more present in classrooms than ever. Automatic Speech Recognition (ASR) offers interesting possibilities for language learners to produce more output in a foreign language (FL). ASR is especially suited for autonomous pronunciation learning when used as a dictation tool that transcribes the learner’s speech (McCROCKLIN, 2016). However, ASR tools are trained with monolingual native speakers in mind, not reflecting the global reality of English speakers. Consequently, the present study examined how well two ASR-based dictation tools understand foreign-accented speech, and which FL speech features cause intelligibility breakdowns. English speech samples of 15 Brazilian Portuguese and 15 Spanish speakers were obtained from an online database (WEINBERGER, 2015) and submitted to two ASR dictation tools: Microsoft Word and VoiceNotebook. The resulting transcriptions were manually inspected, coded and categorized. The results show that overall intelligibility was high for both tools. However, many features of normal FL speech, such as vowel and consonant substitution, caused the ASR dictation tools to misinterpret the message leading to communication breakdowns. The results are discussed from a pedagogical viewpoint.
