Lesson I.A.2: Consonants

Here's a chart, borrowed from the International Phonetic Association, that shows all the humanly possible consonants (not including clicks and such...) arranged by place and manner of articulation:
You'll notice there are many more consonants there than in our previous chart of American English consonants. You've also probably noticed that many of the symbols are NOT what you saw on that last chart. :-) Our next step is to learn those symbols, which make up the International Phonetic Alphabet. For more information on the IPA and some useful charts (many of which I'm borrowing for this lesson), check out the International Phonetic Association's web site. After you've learned the IPA symbols, we'll have to learn ASCII versions of them so we can write about sounds without having to use all sorts of fonts or graphics...
Note: You may wish to print out or bookmark this chart for reference...

For the other consonants on the chart, you can work from the place and manner of articulation to figure out what they sound like. Even though they're not found in English we could certainly use them in TGL if we like. Here's some common ones:
IPA As found in Description ASCII symbol we will use
Bach Voiceless Velar Fricative x
brun or rouge Uvular Fricative R
If there are any other non-English consonants you'd like to incorporate into TGL, we can come up with ASCII symbols for them also.
