Amazon Polly is a service that turns text into lifelike speech. Following the July 30th launch of 8 US English and 3 UK English voices, we are excited to announce the general availability of the first US Spanish (Lupe) and Brazilian Portuguese (Camila) NTTS voices. Both the voices are now available as Neural TTS voices, as well as Standard TTS voices.
