In brief: No

The wax in your ear canal will not alter your voice.
Your own perception of your voice can change with ear wax blocking your ear as this amplifies the internal sounds. The voice you hear normally is through the reasonance of your skull. That is why it sounds different to you than when you hear it on a recording. The wax can alter this reasonance for your own perception of your voice.
