I am a physics student so forgive me if I'm not very precise with the language. I am currently taking an English course, and my teacher is specialized in teaching pronunciation. I am interested in checking if the students are objectively improving. I am interested in the vowels:

æ, ɑ, ʌ, ə, a

because as a Spanish speaker, they all sound very similar. I decided to create a sort of voice-recognition tool (actually it would be vowel-recognition). For this I am using the soundwave of those vowels pronounced by English people. I found this Oxford Corpus with many hours recorded. Here the speakers read some paragraphs.

The problem is that I would spend many hours trimming the audio files in order to extract just the part in which they say the specific vowels I need. I want to ask if any of you knows another Corpus just with vowels, as that would ease my work.

I appreciate your help.

    I think I would advise against that corpus, unless there is a time-indexed transcript to go with the sound files. The problem is that you may not be right in your judgment of which vowel tokens are æ, ɑ, ʌ, ə, or a. – user6726 Sep 27 '16 at 20:17

For corpora in general, you can take a look at the Virtual Language Observatory (VLO). Just search for "English vowels" or something and see if you make a find.

Alternative suggestion: There is a plugin for Praat (the quasi-standard for phonetic analysis among linguists) that provides a script which "extracts the vowels of every selected Sound object and joins them into a new Sound object". I haven't used it myself so don't know how well it works, but you could give it a try. That way, you could continue to work with your existing corpus - read out full paragraphs seem like a more naturalistic, thus more promising resource than recordings of isolated vowels (if there exists such a corpus).

  • I think that plugin should solve my problem. Thanks! – Vladimir Vargas Sep 27 '16 at 21:28
