Once the pandemic concluded, the Foreign Languages Department of a Chilean state university hired a Canadian company to implement a pre-designed language learning system (PLLS). This platform was to be used by all teachers and students, as it contained various activities to develop all four language skills, including pronunciation practice through AI-based voice recognition. This study explores the attitudes of 17 university teachers towards using these pre-elaborated resources, activities, and assessments in their communicative English and German courses. A mixed-method approach was used, involving a survey based on the Technology Adoption Model (TAM) and individual interviews. Descriptive statistics were obtained from the survey responses, and qualitative data were analysed using content analysis techniques. The results indicate that teachers' attitudes towards the PLLS were generally neutral to negative. Instructors expressed their concerns about the system's pre-designed content and perceived functionality. Perceived ease of use and usefulness were rated low, reporting difficulties in navigation and alignment with their teaching styles. Perceived enjoyment received the lowest rating, mentioning issues such as disconnected content and lack of progressive structure. Qualitative data revealed technical problems, increased workload, and concerns about the system's impact on student motivation and learning outcomes. While some positive aspects were noted, the overall attitude towards the PLLS was predominantly negative, highlighting the need for better alignment with pedagogical goals and improved implementation strategies.
