I hear regularly that "User entered your channel" is heard in TeamSpeak. That is not necessary.
Change the Text to speech to say "Lionan has Entered your channel" instead of "User has entered your channel".
You need this addon.
Install it, go to Options -> Notifications, change sound pack to "Clean sounds and short TTS", click ok
Click on the Self Menu at the top. Sound pack, checkmark "Clean sounds and short TTS". You can also set the phonetic sound for your name here.
Have fun with it.
