Potential Paths: Path 1: Utilize Otter.ai for its transcription capabilities, which could be used to convert digital text into audio. The con here is that Otter.ai primary function is to transcribe audio into written text, meaning it doesn't have a built-in feature for text-to-speech but workaround can be made by playing back the transcription which is not ideal.

Path 2: Employ ElevenLabs for its synthetic voice generation capabilities. Use this feature to create a voice that can read out loud the digital text in multiple languages.
