Student participants will use specialized iPad software under the supervision of a speech-language pathologist over the course of 12 months, approximately one session per week, one hour per session.

A specialized iPad application, entitled SpeechPrompts, has been developed to treat prosodic difficulties commonly seen in ASDs. SpeechPrompts provides the SLPs that work with students with ASDs an additional tool to treat prosody. The SpeechPrompts software offers visual support and biofeedback to change prosody. These two tools are not typically available for school-based SLPs.

The effectiveness of the software will be measured in two ways.

1. Perceptual ratings of prosody. Pre- and post-treatment speech samples will be collected from each student participant. These samples will be rated by a member of the research staff on the following prosodic characteristics: rate, rhythm, stress, volume.
2. Questionnaires. Questionnaires will be completed pre- and post-treatment by the students' classroom teacher and speech-language pathologist. These questionnaires will measure the students' use and generalization of skills taught during the intervention.

Usability of software will be measured through questionnaires completed by the speech-language pathologists. Questionnaires will measure ease of software use, utility of software functions, and student engagement during intervention sessions.
