Yes, that is what I'm talking about. Your screenshot shows the error.

It shows that .addFromURI is undefined; this method is in the spec and should be defined.

It shows that .addFromUri is defined; this method is not in the spec.

You might be faked out because the .addFromUri method returns void. (undefined). That's what it should return.

To see the desired result, you need to look at the gramlist SpeechGrammarList object and see if it was augmented:

gramlist.length > 0 // shows a grammar was added
gramlist[0].src     // should show an added URI

Using Chrome on Windows 10:

In an HTML file, I put the following in a script element:

        var gramList = new webkitSpeechGrammarList();

        console.log("SpeechGrammarList check");

        try {
            gramList.addFromURI("foo.grxml");
        }
        catch (e) {
            console.log(".addFromURI() failed");
            console.log(e);
        }

        try {
            gramList.addFromUri("foo.grxml");
        }
        catch (e) {
            console.log(".addFromUri() failed");
            console.log(e);
        }

        console.log("look at speechGrammarList");
        console.log(gramList);

My console log shows:

There's no error log because the errors have been caught with try.

I guess we have to take this in baby steps.

If you look at the 755287.png, you will see the line

VM423:10 TypeError gramList.addFromURI is not a function

That is the current behavior of Chrome, but it is not the correct behavior.
gramList.addFromURI should be a function.

Well, "addFromURI" should be a function because the WebSpeech API says that there's supposed to be a function by that name.

Go to the specification to see that the method/function "addFromURI" is described:

https://dvcs.w3.org/hg/speech-api/raw-file/tip/webspeechapi.html#dfn-addGrammar

Mozilla also talks about the function "addFromURI".

https://developer.mozilla.org/en-US/docs/Web/API/SpeechGrammarList/addFromURI

The method/function is not "addFromUri".

The problem is Blink>Speech has MISSPELLED the function as "addFromUri".

I'll say it again, differently. Blink>Speech has the grammar-from-URI function, but misspelled the method/function "addFromURI" as "addFromUri" [sic].

And a third try: Look at the two function names. Pay close attention. There will be a test later:

* addFromUri - How Blink>Speech misspells the function.
* addFromURI - The function that is defined in the W3C Standard.
* addFromURI - The function that Mozilla describes.
* ........XX - the mismatched characters

Able to reproduce this issue on reported version 61.0.3163.100 , latest canary 63.0.3236.0 using Mac 10.12.6,Ubuntu 14.04 and Windows 10 with steps mentioned in Comment#0. 

Same behaviour is seen from M50[50.0.2166.0]. Hence considering this as Non-regression and marking as Untriaged.

Add use counters for some of Web Speech API

SpeechGrammarList's addFromURI because it doesn't match the spec:
https://github.com/w3c/speech-api/issues/26

SpeechRecognitionEvent's interpretation and emma attributes because
they actually always return null and might be better to remove:
https://chromium.googlesource.com/chromium/src/+/7ad6ea7c2583942e86017bdd6fd5df991f6a05af/third_party/blink/renderer/modules/speech/speech_recognition_event.h#55

SpeechSynthesis#speak() to measure real SpeechSynthesis usage, like
the existing counter for SpeechRecognition#start().
