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 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.

Many thanks!

  • I can't find much either - you may have to create a suite for yourself... which might be a nice / sellable product at the end of it! Let us know how you get on.

    Thanks for looking! Yeah I suspected that's what I'd have to end up doing. The hard part will be getting a broad enough spectrum of languages/accents to avoid bias.

    An interesting question, not deterministic but numberous words with audio samples in many languages can be found at en.wiktionary.org/wiki/Wiktionary:Main_Page
