Frequently asked questions.

How do I localize a podcast for international audiences?
Upload your podcast episode to Humlens. Humlens transcribes the audio, translates the transcript into your target languages, generates voiceover scripts adapted for natural speech, and routes them through reviewer approval. You can then hand the scripts to voice artists or a TTS pipeline to produce the localized episode.
What is the difference between audio translation and audio localization?
Audio translation produces a literal text translation of what was said. Audio localization goes further — it adapts phrasing for natural speech rhythm in the target language, adjusts culturally specific references, provides pronunciation guidance for brand names, and formats the output for voice recording or TTS synthesis.
Does Humlens transcribe podcast audio automatically?
Yes. Humlens transcribes uploaded audio files into text, then translates the transcript into each target language and generates voiceover-ready scripts, eliminating the manual transcription step.
What is pronunciation QA for audio localization?
Pronunciation QA locks the correct pronunciation of brand names, product terms, acronyms, and campaign-specific vocabulary for each locale, preventing voice talent and TTS systems from mispronouncing key terms.
How does text-to-speech (TTS) fit into podcast localization?
TTS services can synthesize translated voiceover scripts into audio automatically without hiring voice talent. Humlens produces clean, formatted voiceover scripts ready to feed into TTS APIs (Google Cloud TTS, AWS Polly, ElevenLabs, etc.) for rapid, low-cost audio localization at scale.
Can I review and edit translated podcast scripts before recording?
Yes. Every translated transcript and voiceover script passes through Humlens's review workflow. Native-speaker reviewers can edit, correct, and approve scripts inline before they are finalized for recording.
