class ScreenReaderMessageGenerator
Defined at line 25 of file ../../src/ui/a11y/lib/screen_reader/screen_reader_message_generator.h
The ScreenReaderMessageGenerator creates screen reader output (node descriptions, hints, etc.),
which is spoken to the user by a tts system. For example, a semantic node which is a button,
with label 'ok', could be represented as: Utterance: 'ok', (with 200 ms delay) Utterance:
'button'.

UtteranceAndContext GenerateUtteranceByMessageId (fuchsia::intl::l10n::MessageIds message_id, zx::duration delay, const std::vector<std::string> & arg_names, const std::vector<i18n::MessageFormatter::ArgValue> & arg_values)Returns an utterance for a message retrieved by message ID. If the message contains positional
named arguments, they must be passed in |arg_names|, with corresponding values in |arg_values|.
Please see MessageFormatter for a full documentation on named arguments.

UtteranceAndContext DescribeCharacterForSpelling (const std::string & character)Returns an utterance that spells out a single character.
1. Pronounces single symbols: For example, the label '.' may be described as 'dot', if the
current language is English.
2. Pronounces capital letters: For example, the label 'A' may be described as 'capital A'.
If neither of these occur, the original label will be returned.
Note that 'character' should only be a single character (its type is 'string' because not all
UTF-8 grapheme clusters can be represented in a 'char').
Virtual for testing.

UtteranceAndContext DescribeListElementMarkerLabel (const std::string & label)Helper method that describes a list element marker.
If the node label only contains a single symbol, instead pronounces a canonicalized version
(e.g., " •" becomes "bullet").
