Voiceover Generation
Submit a script via form and the agent generates studio-quality audio, uploads it to Drive, logs metadata in Airtable.
What it does
Submit your script via the form to instantly generate studio-quality voiceovers that are automatically uploaded to Google Drive. The agent then records the audio duration and logs all details into Airtable so you can easily manage your assets without manual work.
Step by step
- Configure the n8n Form Trigger to accept a single text field for the script input.
- Set up the Google Text-to-Speech node with your service account credentials and select a specific voice model like 'en-US-Neural2-F'.
Where the LLM does the work
- Generate creative prompt instructions for the TTS API to ensure emotional tone matches the script context.
- Draft error handling messages that explain audio generation failures to end-users in plain language.
Watch out for
Google Drive has strict file size limits so you must verify the generated audio does not exceed your quota before uploading.
The fal.ai HTTP request is unnecessary for standard TTS and may introduce latency, so remove it if you only need basic synthesis.
Airtable attachments require valid binary data streams so ensure the Google Drive node outputs a direct file link or buffer correctly.
Tools that fit
n8n Form Trigger Service Initiate workflow via user input
HTTP Request API Call fal.ai ffmpeg for metadata
The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Voiceover Generation: Submit a script via form and the agent generates studio-quality audio, uploads it to Drive, logs metadata in Airtable. ## Specification - What it does: Submit your script via the form to instantly generate studio-quality voiceovers that are automatically uploaded to Google Drive. The agent then records the audio duration and logs all details into Airtable so you can easily manage your assets without manual work. - Trigger: Run manually (Manual · on form submission) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - n8n Form Trigger: Initiate workflow via user input - Google Text-to-Speech API: Generate audio from text - HTTP Request: Call fal.ai ffmpeg for metadata - Google Drive: Store generated audio files - Airtable: Log assets and metadata ## Known pitfalls, handle each one explicitly in your implementation 1. Google Drive has strict file size limits so you must verify the generated audio does not exceed your quota before uploading. 2. The fal.ai HTTP request is unnecessary for standard TTS and may introduce latency, so remove it if you only need basic synthesis. 3. Airtable attachments require valid binary data streams so ensure the Google Drive node outputs a direct file link or buffer correctly. ## Reference implementation https://n8n.io/workflows/5779 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Transcription than Google Text-to-Speech API?
Yes. Google Text-to-Speech API is only the example transcription in this recipe. The same flow works with AssemblyAI, Fireflies.ai, MeetGeek API and OCR.space. Swap the transcription connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for marketers who'd rather brief an agent than start from a blank doc.
