TTS and SR applications
on Aculab Cloud

We have integrated best-of-breed, text-to-speech (TTS) and automatic speech recognition (ASR) functionality with Aculab Cloud voice APIs. Amazon Polly is a deep learning based text-to-speech engine which turns text into lifelike speech. Google speech-to-text is a powerful speech recognition engine which uses machine learning and neural network models to turn speech into text. Each has a wide and growing language coverage, and is seeing heavy investment by a leader in its field.
