How Swiss speech-language pathologists analyze spoken language
What is it about?
Language sample analysis (LSA) is a method speech-language pathologists (SLPs) use to get a broad picture of a person's language. They record someone speaking in a natural situation, write down what was said, and analyze it. In German-speaking Switzerland, people use Swiss German dialect in everyday life and Standard German in more formal contexts. We asked 550 SLPs how they use LSA: how often, with whom, in which language variety, and how they collect, transcribe, and analyze language samples.
Why is it important?
Most research on LSA comes from English-speaking countries. This survey adds a new perspective by examining German-speaking Switzerland, where Swiss German dialect and Standard German coexist in everyday life. We found that 90.4% of SLPs used LSA in the past year — far more than in a recent US survey (60.2%). Almost all clinicians conducted LSA in Swiss German (94.8%) and most also in Standard German (88.1%), while other languages were rarely used (9.1%) despite the high number of bilingual clients. Automatic transcription tools were almost never used (1.0%). LSA was mainly applied with younger children and focused on grammatical features, whereas narrative and conversational skills were analyzed by less SLPs. Nearly two thirds (63.4%) relied on self-designed procedures instead of established protocols. These findings highlight the need for standardized, user-friendly tools and procedures that support LSA in dialectal and multilingual contexts.
