This PR fixes the test of fanyi for Linux.
Part of #86422.

Fancy will pronunciate the word by default. On Linux however, this requires some additional text-to-speech libraries to be installed, hence the test fails. On macOS this works without any additional libraries.
I therefore disabled the acoustic pronunciation, because this isn't useful for testing anyways (and also fixed a typo). This can be also considered unwanted, because a test for this Formula shouldn't cause you Mac to play sounds.

This formula actually already has a Linux bottle, so the test succeeded on Linux in CI at some point.

Hm, you're right!
I have no idea how the pipeline succeeded in the past, since I am able to reproduce this on both vanilla Debian Bullseye and also with the Homebrew Ubuntu 22.04 Docker image used in the pipeline 🤔
Let me check something...

The test on Ubuntu still runs through (https://github.com/Homebrew/homebrew-core/actions/runs/3260182703/jobs/5353576582), even without --no-say, despite failing locally for me.
Closing this, since there seems to be no immediate reason for this patch. Feel free so reopen, if this changes (I'll then remove my testing commit for this to be merged).

If it fixes an issue locally, then I'm fine with merging this.

Great! Reopened & remove test commit.
Forgot to mention: It also prevents you Mac from talking to you while running the test on macOS :D

Sounds like a regression
