This project will build comfortable technology and tools that a wearer can use to record their own speech in natural social settings, play it back, and learn about and reflect on how he sounds. The tools will include automated analysis of pitch patterns, loudness, and timing, to help highlight these non-linguistic features of speech. The toolkit can be used during, or in conjunction with, speech-language therapy for individuals on the autism spectrum to explore and reflect on natural social situations. It will also enable autism researches to collect speech data outside of laboratory settings to quantify progress with language and communication in natural social contexts.
