The occurrence of a colon as a stand-alone token causes g2p to fail with und

[joanise]

If you enter the text foo : bar in Studio-Web or as text input to readalongs align, you get the message:

CLI:

Error: These words could not be g2p'd correctly: ':'. Aborting. Run with --debug-g2p for more detailed g2p error logs.

GUI:

Note the space on both sides of the colon! foo: bar does not cause an error, while foo : bar does.

Reproduce in the CLI

echo "foo : bar" > colon.txt
readalongs align -l und colon.txt /dev/null delme

Reproduce in the Studio-Web

Enter foo : bar in the text box, record any audio and click Go to the next step.
