How it works
- 01
Export the episode from your hosting platform
Buzzsprout, Anchor/Spotify for Podcasters, Podbean, Transistor: all offer episode download in MP3 from the creator dashboard. For episodes published on YouTube (audiocasts): download the audio in MP3 via YouTube Studio (your own videos) or yt-dlp. MP3 at 128kbps or higher guarantees maximum accuracy.
- 02
Upload the episode — any length
VoxScriber accepts files up to 5 GB with no duration limit. 3-hour conversation episodes are processed in 8–12 minutes. Diarization automatically identifies host and guests — no prior configuration needed.
- 03
Repurpose the content in multiple formats
From one episode transcript you can generate: a blog post (use ChatGPT: "Transform into a 1,000-word article"), a newsletter (use Claude: "Extract the 5 key insights"), social media excerpts (LinkedIn, Twitter/X), an e-book or course material, complete show notes, and SRT captions for the YouTube version.
Why transcribing podcasts grows your audience
Podcasts with published transcriptions have significantly greater reach. There are three reasons:
First, SEO. Search engines don't index audio — they index text. Without a transcript, all the valuable content spoken in the episode is invisible to Google. With the transcript published, every insight, name, concept, and question in the episode becomes indexable content.
Second, accessibility. People with hearing impairments, listeners in silent environments (subway, office), and people who prefer reading can consume the content in a way that was previously impossible. This expands your potential audience by 15–20%.
Third, content repurposing. One hour of podcast transcription is raw material for 1 blog post, 1 newsletter, 5–10 social media posts, and complete show notes. Transcription multiplies the value per hour recorded.
Frequently asked questions
How do I transcribe a podcast episode to create a blog post?
Complete workflow: 1) Download the MP3 from your hosting platform. 2) Transcribe in VoxScriber (3–8 min for a 1h episode). 3) Export in DOCX. 4) Paste into ChatGPT with prompt: "Transform this podcast transcript into a 1,200-word blog post. Use H2s for main themes, engaging intro, and CTA at the end. Tone: [conversational/technical/educational]". 5) Review, add images, and publish. Total time: 15–20 minutes per episode.
How do I generate complete show notes from the transcript?
Prompt for ChatGPT/Claude: "Based on this podcast transcript, generate show notes with: 1) Episode summary in 3–4 sentences, 2) Topics discussed with timestamps (use the transcript timestamps), 3) References and links mentioned, 4) Memorable quotes from each guest, 5) Next steps for the listener." Result: professional show notes in 2 minutes.
Do English episodes with international guests work?
Yes. VoxScriber supports 20+ languages including English, Spanish, French, and others. For bilingual podcasts (partly in English, partly in another language), the system detects and transcribes each segment in the correct language. For 100% English podcasts, accuracy is similar to Portuguese (94–96%) with the language-specific model.
How do I use transcription to improve my podcast's SEO?
Strategy: 1) Publish the full transcript on the episode page — this indexes all spoken content in Google. 2) Use the natural keywords that appear in the transcript to optimize the title and meta description. 3) Create derivative articles from the transcript (see FAQ above). 4) Generate social media snippets with the most impactful excerpts. Podcasts with published transcripts have 30–50% more organic traffic than audio-only episodes.
How do I add subtitles to my podcast video on YouTube?
Workflow: 1) Transcribe the episode in VoxScriber. 2) Export in SRT. 3) In YouTube Studio → Content → select the video → Subtitles → Add language → "English (United States)". 4) "Add" next to "Subtitles" → "Upload file" → upload the .srt. 5) Save. Captions are available in 1–2 minutes. Videos with captions have 10–40% higher watch time.
Does diarization work well with 3+ guests on the podcast?
AssemblyAI identifies up to 6–8 distinct speakers with good accuracy when microphones are separate. In podcasts recorded with each participant on their own microphone (professional setup or remote recording), diarization reaches 88–93% accuracy. In roundtable recordings with 4+ people on a single microphone, accuracy drops — in that case, manual speaker identification in the editor (find and replace "Speaker 1" → "Name") is needed.
