Autosofts are typically used by drones, not by people.
The intent here I think is that if you have the correct qualities and echos then it might be possible to slave drones directly to your living persona network and from there emulate autosofts that your drone's on-board autopilot get to share (without actually running them directly on the drones themselves).
A language autosoft would be useful to let your drone's on-board autopilot verbally communicate in a specific language.

Autosofts are specialized programs designed to increase the effectiveness of a drone’s performance. In other words, people have skills, drones have autosofts.
If you (yourself) wish to be able to actually speak foreign languages (in the meat world) then you typically need a skilljack and linguasofts (not autosofts).
SR6 p. 272 Skillsofts - Linguasoft
Linguasofts replicate language skills, allowing a user to speak a foreign language. Linguasofts must be accessed with a skilljack, and the number you can use at once is limited by the skilljack rating.
Having said that, I would personally allow a TM to get a complex form to emulate a basic language linguasoft (without the need for a skilljack). It typically only take about a week to learn a complex form (which is a lot quicker than learning the basics of a completely new language) but beyond that the gain is not huge since it normally only cost 3 karma to learn an actual basic language (that you also don't have to thread or sustain).
Note that you can also use a regular commlink for its already built-in speech-to-text-to-speech translation capability;

Even the most basic of them include ...retractable earbuds, voice access, and text-to-speech and speech-to-text technologies.
