The pronunciation of "self-abased" is [self-uh-beyzd], with the emphasis on the second syllable "abased." The pronunciation of "ashamed" is [uh-shyumed], with the emphasis on the second syllable "shamed." These words are pronounced with a clear distinction between the vowels and consonants, and the emphasis is on the second syllable in each word.

The reason for this pronunciation lies in the English language's phonetic rules and the etymology of these words. "Self-abased" comes from the Latin "abasedus," meaning "brought down" or "humiliated." The "a" in "abased" is pronounced as in "father," and the "b" is a voiced bilabial plosive. The "d" at the end is a voiced alveolar plosive. "Ashamed" comes from the Old English "æscian," meaning "to be afraid." The "a" in "ashamed" is pronounced as in "father," and the "sh" combination is a voiceless postalveolar sibilant. The "amed" ending is pronounced with a diphthong [yuhd], similar to "yumed.

Data supporting these pronunciations can be found in the American English Pronunciation Dictionary by Ann Cook, which provides phonetic transcriptions for words in American English. According to the dictionary, "self-abased" is transcribed as [self-uh-beyzd], and "ashamed" is transcribed as [uh-shyumed]. These transcriptions align with the phonetic rules and the etymology of the words, confirming the correct pronunciation.
