Do all summaries have an audio version?

All summaries released from 2020 onward include an audio version.

We have more than 5000 audio summaries released before 2020, including the top 100 titles in each language (not including Russian and Chinese or literary classics).

If a professionally recorded audio summary is not currently available, you may listen to the summary using the text-to-speech function on your mobile device. Please view the settings on your mobile device to manage your text-to-speech preferences.

In our search function, you can filter results to view only those summaries with a professionally spoken audio file. The headphones symbol can recognize these.
