1. First mouth and tongue muscke exercises, then focusing on extending the first vowel of each word, doing that with all the vowel combinations in random vowel and consonant combinations such as "ABA", "ABE", ..."EZO"... But writing them like this won't make much sense because English isn't a phonetic language, whereas Turkish is. There were also other exercises such as reading tongue twisters with the vowel extension technique, or letting out vowels in a single, long breath. 2. Let's say the word is "laboratory". You'd say it like "Laaaaboratory". Or "Aaaaarmchair". The long vowel is constant and uninterrupted, whereas all other syllables are fast. Also you'd link certain words. Example: "My automobile" would be like "Miiiiiyautomobile" Again, it's hard to explain because English isn't a phonetic language, but the vowel sound is extended and if the last sound is a consonant and the following word'a first sound is a vowel, then you link them as if they're a single word. 3. They're in Turkish. But basically they were short stories in which someone was using the 'first vowel extension technique'. The exercise was either whispering or speaking out loud the same way, half a second affer the voice.
