Brief Summary
This first study will enroll 3 groups of patients with vocal fold nodules that will receive different schedules of ambulatory voice biofeedback (100% frequency feedback, 25% frequency feedback, summary feedback) to avoid their upper 15th percentile of vocal loudness.

Outcome Measures
Primary Outcomes (1)
Percent Compliance
Percentage compliance is the amount of voiced time patients spent below their biofeedback threshold divided by the total amount of voiced time. Each patient's biofeedback threshold was individually established as their 85th percentile of vocal intensity. Patients were asked to avoid loud voicing, i.e., anything at their 85th percentile or higher. During biofeedback, patients were cued every time (100% frequency) or every 4th time (25% frequency) the voiced louder than their 85th percentile; or provided summary information (their percentage compliance) after every 2 minutes of voicing (summary feedback). During short-term retention monitoring, patients were asked to not voice loud (over or equal to 85th percentile) the next day and the biofeedback was turned off. During long-term retention monitoring, patients were asked to not voice loud one week later without biofeedback.

100% frequency
EXPERIMENTALSome patients will be assigned (via block randomization) to receive ambulatory voice biofeedback (100% frequency - vibrotactile cueing every time the participant exceeds a vocal intensity threshold). Voice monitoring will be conducted for 3 days (device automatically turns off after 42 minutes of voicing): Day 1: biofeedback will be active all day , Day 2: the day after Day 1, no biofeedback, just monitoring to test short-term retention. Day 3: 7 days post-Day 1, no biofeedback, just monitoring to test longer-term retention.
25% frequency
EXPERIMENTALSome patients will be assigned (via block randomization) to receive ambulatory voice biofeedback (25% frequency - vibrotactile cueing every 4th time the participant exceeds a vocal intensity threshold). Voice monitoring will be conducted for 3 days (device automatically turns off after 42 minutes of voicing): Day 1: biofeedback will be active all day , Day 2: the day after Day 1, no biofeedback, just monitoring to test short-term retention. Day 3: 7 days post-Day 1, no biofeedback, just monitoring to test longer-term retention.
Summary feedback
EXPERIMENTALSome patients will be assigned (via block randomization) to receive ambulatory voice biofeedback (summary - no cueing, statistics shown every 2 minutes of voicing). Voice monitoring will be conducted for 3 days (device automatically turns off after 42 minutes of voicing): Day 1: biofeedback will be active all day , Day 2: the day after Day 1, no biofeedback, just monitoring to test short-term retention. Day 3: 7 days post-Day 1, no biofeedback, just monitoring to test longer-term retention.
Interventions
Subjects will be provided cues regarding their vocal behavior in daily life. The cues will either be: 100% feedback = a vibrotactile cue on a smartwatch every time the patient voices incorrectly... 25% feedback = a vibrotactile cue on a smartwatch every 4th time the patient voices incorrectly... Summary feedback = the patient's overall compliance (percentage of voiced time within desired limits) will be presented via a smartwatch every 2 minutes of voicing.
Eligibility Criteria
You may qualify if:
- Patients with vocal fold nodules
You may not qualify if:
- Non-English speakers are excluded because prompts on the smartphone app are only available in English
