This should already work as you expect if the synthesiser correctly exposes the language and you have automatic language switching enabled. Can you confirm at least the second point?

Comment 2 by kredh on 2014-06-20 10:11
No, automatic language switching is off (I prefer to do it myself, when given a chance, partly since I don't use the same synthetizer for both languages).

Comment 3 by jteh on 2014-06-20 11:05
If you disable automatic language switching, NVDA trusts only its own user interface language, not the synthesiser or the document. If you want the symbol language to work as you expect, you need this setting enabled.

Comment 4 by kredh on 2014-06-20 11:32
I just tried and it works. The trouble is, automatic language switching should perhaps remain independent from the letter and puctuation names. If the information can be deduced from the synthetizer, couldn't it just use it without the "automatic language switching" enabled?

Comment 5 by jteh on 2014-06-20 11:54
One reason a user might not want to use automatic language switching is that a synthesiser they use does not correctly report its language, which unfortunately does happen with some synths. This is why NVDA resorts to the interface language in this case.

I understand that you choose to switch synths yourself. However, this doesn't explain why having this option enabled is a problem for you. If you're going to switch anyway, the automatic switch might be wasted, but shouldn't be problematic. Can you explain the problems this causes for you?

Comment 6 by kredh on 2014-06-20 12:09
There are two reasons why I don't like to enable this option:

1. I'm using two different synthetizers (Eloquence in French and a voice from Vocalizer in English). Therefore, if I enable this option in French and it switches in English (when I browse an English website, let's say), it still is the English voice for Eloquence, which is not the one I really like in this language.
2. When a web page contains information in both languages (and probably in other languages, as well), the synthetizer keeps on changing. And it's not always required (say, some text looks like English to it but, it's short, it works in French too, and as a matter of fact it was intended as a French text). The change of synthetizer from line to line (even on a single line) is quite disturbing, but the unconsistency is worse.

I'm not asking that it be fixed, I can imagine how hard this feature (automatic language switching) is to implement in the first place. But the symbol names could still be in the synthetizer language without it enabled, I think, if the synthetizer is explicit about the language it uses currently.

Replying to kredh:

1. I'm using two different synthetizers (Eloquence in French and a voice from Vocalizer in English). Therefore, if I enable this option in French and it switches in English (when I browse an English website, let's say), it still is the English voice for Eloquence, which is not the one I really like in this language.

If you're browsing an English site, I'm guessing you have to switch to Vocalizer manually anyway. Therefore, I don't follow why Eloquence switching to English is problematic, since you have to override it either way. What am I missing here?

1. When a web page contains information in both languages (and probably in other languages, as well), the synthetizer keeps on changing. And it's not always required (say, some text looks like English to it but, it's short, it works in French too, and as a matter of fact it was intended as a French text).

NVDA currently only switches languages if the document explicitly specifies the language for a given piece of text. It's odd that the author intended this, even though you note this is not ideal.

But the symbol names could still be in the synthetizer language without it enabled, I think, if the synthetizer is explicit about the language it uses currently.

It can't for several reasons:

1. I seem to recall that some synthesisers explicitly specify an incorrect language. NVDA can't distinguish these cases.
2. Some multi-lingual synthesisers automatically switch between languages depending on the text. For example, an Arabic synthesiser might speak Arabic for Arabic characters but English otherwise, since these languages use very different characters. In this case, the synthesiser will always report its language as Arabic, but the user might actually prefer to have NVDA's interface in English and read English characters, etc.

If this does indeed need to be configurable, we'd need to introduce another option. I'm very reluctant to do this because this will be confusing for users and describing it is extremely difficult. This is why I want to make sure we fully understand your use case.

Comment 8 by kredh on 2014-06-20 12:46
It seems that fixing it would bring more trouble than anything and the bug is not that big either (if you call it a bug at all). And anyway, I realized that the same problem held true for HTML elements (like link, lists, edit fields). So in this case, changing the NVDA language remains the best solution (and changing the NVDA language through profiles is probably not urgent and perhaps not even possible).

Anyway, I think it's a rather individual need and won't benefit much for the community itself, considering the time that would be necessary to fix it. So I think you can close this ticket.

Comment 9 by jteh on 2014-12-02 06:06
We're going to add a new option called something like "Speak symbols using voice language". If Automatic language switching is enabled, this will be force enabled too.

Comment 11 by vgjh2005 on 2014-12-16 12:32
Hi:
I like this feature very much. Thanks for developing this function.
I am using vocalizer express to test this new feature. I find a problem at this time.
Step to reproduce:
1.Uncheck Trust voice's language when processing characters and symbols;
2.Checked Detect text language based on unicode characters (experimental)
and Ignore numbers and common punctuation when detecting text language (experimental) in Automatic language switching settings dialog;
3.Set the default synthesizer to tiantian that is a Chinese voice.
4.Paste the symbol ° in notepad;
5.Press arror key to read it.
expective: read as 度
actually： Read as degrees
Why? I don't decide that this is a bug, however, that I cannot realize this function is also possible. Please let me know.
Thanks!

Unless I'm missing something, this makes sense and is exactly what this feature is supposed to do. You've chosen not to trust the voice's language, so unless the document specifically indicates otherwise, NVDA will use NVDA's interface language for symbols rather than asking the voice which language to use. If you want to trust the language reported by the voice, you need to enable the option.

Comment 13 by vgjh2005 on 2014-12-16 17:55
Hi:
I've known it for comment above. I think I should tell you that my interface language is simplified Chinese. When I unchecked "Trust voice's language when processing characters and symbols",the symbol ° should be read in Chinese. But actually it was read in English.
I think that the reason is that vocalizer express addon do language switching by itself, and the new option is not effect in vocalizer express. Thanks!

Comment 14 by jteh on 2014-12-16 23:25
You are correct; Vocalizer's auto language switching stuff is not at all integrated with NVDA itself, so NVDA is completely unaware of it and can't affect it in any way.

Comment 18 by leonarddr on 2015-02-16 21:36
I wonder, shouldn't the interpunction/symbol pronunciation prefferences dialog respect this option, I.E. load the symbols of the corresponding voice language when this option is enabled? Things can be very unclear when one is editing symbol pronunciation rules which aren't applied due to the selected voice talking another language. I wouldn't mind about this if trust voice language wasn't enabled by default , but now, it seems an issue to me.

Comment 19 by jteh on 2015-02-18 03:55
I agree this is a problem which should be fixed. However, this is not new. Previously, the same occurred when you had automatic language switching enabled (which was the default). Filed #4930 for this.

Hi,
Some zh-TW users report:
Checked "Trust voice's language when processing characters and symbols" caused NVDA to use zh_CN's characters and symbols description.
expected: use zh-TW's files

That suggests the voice reports it is zh_CN instead of zh_TW, which suggests a bug in the voice.
