📝 About this app
Analyse your voice pitch, associated voice gender, & volume in real-time with the ability to record and replay the last 10 seconds. Essentially a voice analyser for transgender, LSVT, singers, and voice therapy patients to help improve the quality of their voice.
-View a graph of your voice pitch/associated gender in a real-time!
-Phonetically balanced sentences for you to read
-Listen to tones of specific pitches for you to mimic
-Record & playback without saving files to your device
-Real-time volume analysis
-Transgender & non-binary friendly
Please note; this app does NOT change the pitch of your voice, it only provides visual feedback specifically tailed for use as part of voice therapy!!!
The voice pitch analysis works best with an external microphone! It will work without an external microphone but please be-aware that results may vary as the voice pitch analysis requires a relatively quiet environment and some phone microphones can pickup a lot of background noise.
This tool is designed to act as a voice recorder/playback/analyser tool but with useful information such as voice pitch, tones, & volume with resonance and phonetics to be added at a later date. It is mostly intended for use as part of voice therapy, and users should be aiming to use the tool for about 5 minutes a day over several months. It does not provide lessons or guidance, it is intended to be used as a tool to assist with voice therapy and not as a replacement for voice therapy.
