[espeak-ng:master] New Comment on Issue #690 Testsuite fails on various archs
By rhdunn:

The failing test is running the following command:

espeak-ng -xq -v grc "Οἱ δὲ Φοίνιϰες οὗτοι οἱ σὺν Κάδμῳ ἀπιϰόμενοι.. ἐσήγαγον διδασϰάλια ἐς τοὺς ῞Ελληνας ϰαὶ δὴ ϰαὶ γράμματα, οὐϰ ἐόντα πρὶν ῞Ελλησι ὡς ἐμοὶ δοϰέειν, πρῶτα μὲν τοῖσι ϰαὶ ἅπαντες χρέωνται Φοίνιϰες· μετὰ δὲ χρόνου προβαίνοντος ἅμα τῇ ϕωνῇ μετέβαλον ϰαὶ τὸν ϱυϑμὸν τῶν γραμμάτων."

and comparing the output with a reference output string:

hoI_: d'e_: f_: 'o_: 'i_: n_: 'i_: l'et@_|_|f_|_:_: 'e_: s_: h'u:toI_: hoI_: s'yn_: k'admOI:_: 'a_: p_: 'i_: l'et@_|_|f_|_:_: 'o_: m_: 'e_: n_: 'o_: 'i_: es'E:gag,on_: d_: 'i_: d_: 'a_: s_: l'et@_|_|f_|_:_: 'a_: l_: 'i_: 'a_: 'es_: tu:s_: ell'E:nas_: 'aI_: d'E:_: 'aI_: gR'ammat,a_:

If you run the command with -X instead of -x you will get more detailed output of what eSpeak is doing.

Even in the working version, I can see something strange happening. I don't see any obvious issues with the translate output, but the pronunciations contain parts such as l'et@_|_|f_|_:_: 'e_: s_:, i.e. "letter f e s". It normally does that when the word is unpronouncible, but I don't see that in this instance.

There may be a bug in some of the functionality that the grc dictionary is using when translating that text that happens to behave slightly differently on those platforms.

So the difference starts with

Translate 'ϰαὶ'
Translate 'ϰ'
Translate 'α'
 36	α       [a]

Translate 'ὶ'
 22	ὶ      ['i]

Translate 'δὴ'
 36	δ       [d]

 22	ὴ      ['E:]

on arm64 while we have

Translate 'ϰαὶ'
 57	αὶ    ['aI]
 36	α       [a]

on amd64. Do you have any idea of which kind of test or function could make espeak-ng process letter by letter rather than grouped by 3 letters?

Thanks.

The word "φοὶνιϰες" looks like it cannot be pronounced -- the translation does not process the ϰ letter, then proceeds to translate each letter individually. That is consistent with the output, although I don't know why there isn't an unpronouncible message like with English.

Words spelled out after reaching a specific letter: * φοὶνιϰες [ϰ] amd64, arm64 * απιϰὸμενοι [ϰ] amd64, arm64 * διδασϰὰλια [ϰ] amd64, arm64 * ϰαὶ [ϰ] arm64 only -- this is the cause of the difference and thus the test failures * δοϰὲειν [ϰ] amd64, arm64 * φοὶνιϰες [ϰ] amd64, arm64 * ϕωνῂ [ϕ] arm64 only -- this is the cause of the difference and thus the test failures * ϱυϑμὸν [ϱ, ϑ] amd64, arm64 -- amd64 processes ϱυ and then aborts on the ϑ; arm64 is aborting immediately

So it looks like there is an issue with the rules for those letters, causing those words to be spelled out instead of pronounced phonetically. Those letters are also not pronounced when spelling them out.

For the arm64 and other platforms, it looks like the difference is when the affected letters occur at the start of a word.

In the grc_dict file there are no entries for the letters that have issues -- no .group or .replace entries. For example, the letter ϰ is Unicode character U+03F0 (GREEK KAPPA SYMBOL) -- a cursive version of kappa [κ] -- is missing.

This is why the translation is aborting part way through, although I don't understand why amd64 and arm64 have a different behaviour when a missing letter is at the start of a word.

The fix for this test is to map the cursive Greek letters to their non-cursive counterparts.
