This is very much not true.

Telephony is significantly less latency sensitive than real time audio processing, it’s also significantly less taxing since you’re dealing with a single channel.

The level of compression and audio resolution required are significantly different too. You can tune codecs for voice specifically, but you don’t want compression when recording audio and can’t bias towards specific inputs.

They’re only similar in that they handle audio. But that’s like saying the needs of a unicycle and the needs of an F1 car are inherently the same because they have wheels.
