Changes in version 0.1.6 - list_voices() can now list voices for all language codes (@muschellij2, #6). All voices (for all language codes) are now shown by default. Use language = "en-US" to replicate the previous default. - list_voices() has new arguments engine (to filter on engine types) and include_additional_languages (to find bilingual voices with specific additional languages). - synthesize() and get_synthesis() have new arguments engine (to specify the engine type) and language (to specify the language code when using bilingual voices). - In synthesize() and get_synthesis(), arguments rate and lexicon are deprecated and replaced by sample_rate and lexicon_names. - In synthesize() and get_synthesis(), the default sample rate is no longer 22050 Hz. Instead, AWS will pick the appropriate default based on the voice, engine and output format. - Speech synthesis now fails with a useful error message when AWS returns an error.
