Betalga is not a commonly used word, but it's often misspelled due to its unusual pronunciation. According to the IPA phonetic transcription, the correct spelling of the word is /bɛtælgə/. It starts with the open-mid front unrounded vowel /ɛ/ followed by the voiceless dental fricative /θ/ and the short a sound /æ/. The final syllable starts with the voiced velar plosive /g/ and ends with the schwa sound /ə/. Thus the correct spelling of this word should be kept in mind while writing.
