The spelling of the word "Rotche" may seem unusual, but it can be understood through phonetic transcription. Its IPA pronunciation is /rɑtʃ/ which shows that it is made up of four sounds: a voiced alveolar trill /r/, an open back unrounded vowel /ɑ/, a voiceless palatal affricate /tʃ/, and finally another voiced alveolar trill /r/. This spelling represents a regional variation of the word "roche" which means rock or hill in French.
