I am attempting to evaluate several audio codecs to determine their suitability to transcode speech for use with voice assistants such as Amazon Alexa and Google Assistant.
From my own research there doesn't seem to be much, if any test samples available that could be used for this purpose. Especially for the keyword detection such as "Alexa" or "Hey Google".
Ideally I'm looking for samples that I can use that will return a deterministic response from the different assistants. For example: "What year was [X celebrity] born?"
Does anyone know if such a library of test samples exists? Either commercially or free to use.
