Sonneta Voice Monitor|醫療線上App不用買-HotApp4Game

Monitor Vocal Pitch and Sound Level• Measure vocal pitch (fundamental frequency) and sound pressure level (SPL).• Real-time meter display and moving chart provide you with feedback for singing or speech therapy exercises.• Designed specifically for measuring the human voice — talking, singing, shouting, and humming. Sonneta Voice Monitor will not measure the frequency of non-vocal sounds such as whistling, musical instruments, etc.• Based on a state-of-the-art algorithm used in voice research. This is not a simple “instrument tuning” app.Measure Phonation Time• Automatically measures the duration of each phonation (vowel sound).• Allows you to set target durations for visual feedback.Record Samples• Record samples of your voice for later playback.• A recordings list organizes samples by date.• Option to give a title to each recording.• Save samples to show or email to your speech therapist or voice coach.• View statistics for each recording including average, minimum, maximum, range, and standard deviation for pitch and sound level; maximum phonation time.Play Back Recordings to Review Pitch, Sound Level, and Phonation Time• Select a sample from the recordings list to play back over the speaker.• Pitch, sound level, and phonation time are displayed during playback and scrubbing.Set Prompts and Alerts• Speech therapists and voice coaches can record prompts for their clients to play back during practice.• Record any number of prompts and select them by title.• To play a prompt, simply tap the prompt button during practice.• Therapists can also set limits for pitch and sound level. Users are alerted if they exceed the limits.Absolute Accuracy• Voice-activated calibration allows you to measure absolute sound level no matter where you place your iPhone or iPad. It even works with external microphones. Calibration requires a sound level meter (sold separately).• You can use the app without calibration to measure relative sound levels.• Pitch is measured in Hertz or semitones and does not require calibration.
