On some Wikipedia pages you can find “click and listen” buttons associated with some vowels. If you look at Cardinal vowels you can see the familiar chart and underneath it a table listing all the vowels. Each entry in this table takes you to a separate WP article on that vowel (you may feel that one article per vowel is a bit excessive), and in the “info-box” at upper right on each page is a button that gives you the audio. I do not know who recorded these vowels, nor even if they were all recorded by the same person. At this stage I prefer not to comment on the quality. If you go to IPA vowel chart with audio you can hear the same recordings (I think) just by clicking the appropriate place on the chart. However, there are now additional vowel symbols on the chart: these are vowels which are not included in the IPA’s version of the Cardinal Vowel chart, but which WP seems keen to include. Some of these vowels are ones which I don’t think I have ever attempted in my life – not in public, anyway. These “off-piste” vowels do sound very strange to my ears. On the Talk page corresponding to this topic I have already complained about adding extra vowels to the IPA vowel chart, and got a reasonably sympathetic response. I notice on that page that “ … the article on the near-close central rounded vowel [ʊ̈] or [ʉ̞] doesn't have a recording yet”. Now there’s a challenge for someone to take up!
There’s a lot more to say on this subject, and I’ll return to it. After that, there’s a lot to say about the article IPA non-pulmonic consonant chart with audio
