Voice Tools funktioniert nicht

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!  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.  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!!!  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.  Analyse your voice pitch, associated voice gender, & volume in real-time with the ability to record and replay the last 10 seconds.  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.  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.  The voice pitch analysis works best with an external microphone!  No voice recordings are saved or leave the device.  This app is available in two flavors; a free advert supported version, and a paid advert-free version.  You can remove the adverts via an in-app purchase in the settings screen.  Help us to improve this app, if it doesn't work, or you have any ideas to help us improve please drop us an email so that we can improve things in the next release!
