Deconstructing Voice Therapy: Towards Enhanced Communication Outcomes

Participants in the hierarchical version of Conversation Training Therapy (CTTH) will receive four weekly sessions of voice therapy. This approach gradually increases the difficulty of speaking tasks-from simple sounds to full conversations-based on the participant's progress. The therapy begins with basic awareness and speech sounds (e.g., consonant-vowel pairs), then progresses through words, phrases, and sentences, culminating in natural conversation. Each level must be completed with at least 80% accuracy before proceeding to the next one. The structure is modeled after traditional voice therapies like resonant voice and aims to help participants succeed early and reduce mental fatigue. Daily homework includes seven short (2.5-minute) practice sessions, aligned with prior research showing this is a realistic and effective amount of practice.

The therapy includes four weekly sessions and several key techniques: Clear Speech: Speaking clearly, like leaving an important voicemail. Awareness Training: Paying attention to how the voice sounds and feels in the mouth and face. Negative Practice: Switching between their "bad" voice and "good" therapy voice to recognize and improve differences. Embedded Gestures: Briefly holding certain speech sounds to reduce vocal strain and boost clarity. Prosody and Projection: Working on pitch, rhythm, and speaking louder through better technique. Participants practice these skills throughout the day using a mobile app to track their progress and record a weekly sample. Unlike hierarchical models, components in CTT can be introduced in any order based on individual needs, making it flexible and personalized
