I cannot not talk about pronunciation, especially for English. To save time typing special symbols for IPA, I took to using SAMPA. It's fun and easy to learn.
For example, today I wrote about the common systematic English mispronunciations by native Mandarin speakers:
/I/ or /i/ (not long enough) for /i:/: seek -> sick; bee -> 必
/in/ for /In/: been -> 必+n
/{/ for /E/: bed -> bad
/E/ for /eI/: take -> tech
I created a handy conversion chart.
I use SAMPA as the wide phonetic transcription throughout this website because it is pure ASCII, to save time entering quirky symbols for IPA.
