As noted by the unofficial Google Operating System blog, Google could soon add the option to select a dialect for certain languages in its text-to-speech feature within Google Translate. The option is currently hidden in Translate’s source code, according to the report, and it would allow users to hear various dialects like American, British, and Australian for English.
The text-to-speech feature will allow you to select the dialect for languages like English, Spanish, Portuguese and Chinese. It’s nice to compare American English, British English and Australian English.
The report also noted hints of other features that aren’t currently available, including phrasebook and dictionary features.
