This page should allow the user to preview the transcription before adding to the lexicon. With the latest version of the TTS-server, I have gotten this to work with at least Swedish.

Transcription should be validated before the it's sent to be synthesized .

Since the transcription should be given in IPA, the preview process will likely be something like:

1. Map IPA -> SAMPA
2. Validate SAMPA (not sure if this is necessary, see question below)
3. Synthesize the transcription

Feedback will be given in 2 and 3 if there are any errors.

Wikispeech-STTS, is it possible for a transcription that has been successfully mapped from IPA to a certain SAMPA set to not be valid for that set?

Universal Language Selector adds a nice way of typing IPA that can be used for the transcription field. When enabled, this adds a little popup menu below just about any text field where input method can be selected. The one called "International Phonetic Alphabet - X-SAMPA" seems easy enough to use; the special characters can be found on ⇧ and/or AltGr + key. I haven't found any information like complete key map yet.

Also relevant for T180701: Editor dialogue.

I've managed to salvage my experimental code and now have a solution up and running locally. What remains is to clean up the code and add stuff like message strings.
