When finding yourself in a noisy environment it's difficult to listen to voice messages that are sent to you. The same is true when sitting in class for example. Voicer for WhatsApp turns voice messages into written text at the push of a button. Simply highlight the voice message in your messaging client by long-pressing on it tap the "Share"-button and select "Voicer for WhatsApp" from the list of possible sharing targets. The voice message will then appear as written text!

You can use the app's settings menu to change the recognition language. The app supports 50+ languages.

If you want to continue using the app after the first 4 day free trial period there is a $1.99 fee.
