Google Cloud Speech-to-Text

Google Cloud Speech API is a part of Google Cloud infrastructure. It allows converting human speech into text. This API supports more than 110 languages. The system supports customization in the form of providing the list of possible words to be recognized (this thing is especially useful if you want to use speech recognition in some devices or other situations where the list of possible words is limited). API can work both in batch and real-time modes. It is stable against side noises in the audio. For some languages the filter for inappropriate words is available. The system is built using deep neural networks and can be improved over time. The files you want to process can be directly fed to the API or be stored on the Google Cloud Storage.

Amazon Transcribe

Amazon Transcribe is a part of the Amazon Web Services infrastructure. You can analyze your audio documents stored in the Amazon S3 service and get the text made from the audio.

Amazon Transcribe can add punctuation and text-formatting. Another valuable function provided by this service is the support for telephony audio. It is because the audio from the phone conversations often has low quality. So, the developers of Amazon Transcribe considered, that they have to process this type of audio in a specific way. The system adds timestamps for each word in the text. So, you will be able to match each word in the text to the corresponding place in the audio file. It is expected that the API will be able to recognize multiple speakers and label their voices in the text soon. Creating custom words also should be available in a short time. Users will be able to explicitly add, for example, names of their products, or some other specific words.

Eden AI

The most effective way to compare these two engines is to test them: the performance can truely depend on your data and your needs. It is to facilitate the testing and use of this type of engine that we have developed Eden AI: a unique API connected to the best AI engines and combined with a powerful management platform.
