Re: SpeechRecognitionAlternative.interpretation when interpretation can't be provided

I propose that last sentence be replaced by "If no semantic meaning can be
determined, the attribute must return 'undefined'."

The reason being that this simplifies the developer's coding.
The interpretation attribute is of type "any" because it typically returns
structured data.

'undefined' allows the developer to perform a simple check to determine if
the interpretation is present, and if not, simply use the transcript
attribute, which is always a string.

Conversely, the developer would have to check for the type of the object(s)
returned in the interpretation attribute, requiring significantly more
complex code.
