Discover how to build an end-to-end pipeline for automated podcast localization using OpenAI's API suite. We'll explore a Kotlin-based solution that transforms English podcasts into Russian versions while preserving the original tone and style. The pipeline combines Whisper for transcription, GPT-4 for text refinement and translation, and TTS for voice synthesis. We'll dive into prompt engineering techniques, audio processing specifics, and the challenges of maintaining content authenticity across languages.
