Sonneta Voice Monitor is used by speech-language pathologists, voice coaches, and their patients and students. It is the only app of its kind to use a pitch detection algorithm published in a leading peer-reviewed journal in voice research. Sonneta Voice Monitor is used by clinical faculty and researchers at over 30 universities and teaching hospitals. 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 hands-free 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. Measure Phonation Time • Automatic hands-free measurement of phonation (vowel sound) duration. • Allows you to set target durations for visual feedback. • Useful in conjunction with LSVT under supervision of a qualified clinician. Record Samples and View Statistics • Record samples of your voice for later playback. • A recordings list organizes samples by date. • Option to give a title to each recording. • 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. Organize, Share and Export Your Data • File your recordings and data by client, by voice exercise, or any way you like. • Export measurements and statistics to a spreadsheet. • Share your recordings with your speech therapist using Mail, Messages, or AirDrop (provided you both have the latest version of Voice Monitor installed). 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. • Therapists can also set limits for pitch and sound level. Users are alerted if they exceed the limits. • Prompts, limits and phonation targets are saved independently for each client file you create. 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.



  • Inaccurate pitch analysis

    For an app that cost 35.99, I expect better quality. It was reading inaccurate pitch frequencies. They were way off.
  • Great for Speech Therapy

    I've tried multiple voice apps for our patients receiving voice therapy. They were either free or low cost, but none of them provided what we needed. For our patients with monotone or low volume, this app allows recording with playback and good statistics which are very useful for baseline documentation and later comparison as therapy progresses. The price is higher than the typical apps but well worth it compared to other systems out there. I highly recommend this program!
  • This is just what I was looking for!

    By ChutesAndLadders
    I've been looking for something that I can use to monitor my voice, while doing my speech therapy homework. I haven't really found much online other than programs such as Pratt which has a steep learning curve and doesn't give live feedback and another program called Sing and See, which dose provide live feed back, but doesn't provide the same level of functionality as the Sonneta Voice Monitor, but Sing and See is targeted towards singers and not people undergoing speech therapy. The Sonneta Voice Monitor gives me the ability to set my pitch range and to limit the decibels it which helps cut out background noise, when taking sample recordings. It also has the ability to analyze the recordings that you take and show the median pitch, which is what you need to know for your target, when you are trying to speak in the appropriate pitch range for your gender, along with other pitch and decibel data related to the sample file.
