The focus of this collaboration is a corpus-based analysis of mouthings in DGS, bringing together the perspectives of various researchers with a keen interest in the topic of mouthings. The analysis is based on the annotated data from the “MEINE DGS – annotiert” of the Hamburg DGS Corpus (Konrad et al., 2020). The DGS Corpus already contains extensive mouthing annotations; however, these are tied to the main glosses. This means that mouthings without manual glosses or mouthings produced by the addressee as feedback are not annotated in the corpus. Moreover, there is no information on the form or function of mouthings. In this collaboration, we aim to achieve the following objectives:

• A representative study on the use of mouthings in DGS based on DGS data from the Public DGS Corpus (Konrad et al., 2020) (e.g., How frequently do mouthings occur in DGS?),
• Consideration of socio-cultural (region, age, or gender) and communication-specific variation (language register, discourse context) (e.g., How often is the DGS sign HOUSE produced with a mouthing during its initial introduction compared to later in the discourse?),
• Modeling of mouthings (e.g., What is the probability that a specific mouthing co-occurs with a particular sign (nouns versus verbs, lexical versus productive signs)? What is the relationship between mouthing and word class in DGS? What is the tension between mouthing and mouth gesture in DGS?).

We aim to combine two approaches:

1. targeted search and analysis of individual DGS gestures: a list of about 20 noun-verb pairs will be generated and analysed for their co-occurrence with mouthing in the whole corpus,
2. in addition, we will annotate and analyse several hours (about 10 hours) of spontaneous DGS conversations in the entire MEINE DGS part (Konrad et al., 2020) and analyse them with regard to the use of mouthing without manual glossing and as feedback.
