A note on entertainment apps

There are a number of apps that can tune your voice to sound more masculine or feminine. These can be fun, but relying on a temporary voice shift may cause problems. Some people dislike their unfiltered voice after hearing it through these apps. If you plan to use a filter for online interactions, it can be an issue if your offline voice does not match when you meet someone in person.
