This paper reports on work in progress investigating lip and vertical larynx movements that occur in smiled speech and laughter. A controlled speech corpus in terms of vowels spoken at various degrees of retraction of lip corners is recorded as well as a corpus of induced naturally smiled speech. A combined motion capture and image processing technique is applied to track marked points on the lips and vertical larynx position synchronously while simultaneously recording the audio speech signal. Data will be analyzed to investigate correlations between lip shape and larynx position in smiled speech and to find effects of smiling on audio speech both differentiating between voluntarily spread lips and induced smiles each at various levels of intensity. Some data of spontaneous laughter is included, too.
