We want to learn about a new way to help people make the /s/ sound, like in the word "snake." We will be studying a way to teach the /s/ sound that uses very short speech sessions. This study will also collect recordings from people as they say words with the /s/ sound. We will listen to these recordings and check if the words are said clearly.
In the first visit, we'll do a speech lesson on how to make a clear
/s/ sound. We will also have the participant say some words while we record them talking. If they are a good fit for the study, we will invite them to do a second visit. In the second visit, they will name some pictures, answer some questions, repeat words and sentences, and do some mouth movements. After the second visit, if they are a good fit for the study, we will invite them to do the speech lessons. The speech lessons will each take 10 minutes, and they will have lessons 4 times a week for 8 weeks. They will do these lessons on video chat. They will be randomized to either start right away or after 8 weeks. We'll also ask them to participate in 3 other visits to track progress by having them repeat words with /s/.
