The spelling of the word "babl" may seem unusual, but it can be explained using IPA phonetic transcription. The first sound in the word is the voiced bilabial stop /b/, which is followed by the open central vowel /æ/. The next sound is a voiced labiodental fricative /v/, and finally, the word ends with another voiced bilabial stop /b/. Although the spelling "babl" may differ from traditional English orthography, it accurately reflects the pronunciation of the word.
