Experiment with all of the Chirp 3 HD voices.\n\n## The uses are endless! Try creating voiceovers for your videos, generating audio versions of your articles, or building interactive voice responses for your applications.\n\n\n### How it works \u2699\ufe0f\n* The workflow is kicked off by a **Form Trigger** where you input your script, and choose a voice and language.\n* We then use the **HTTP Request** node to send your text to Google's Text-to-Speech API.\n* Google's AI processes the text and sends back the audio data in base64 format.\n* A **Convert to File** node transforms this base64 data into a binary audio file.\n* This audio file is then uploaded to **Google Drive**.\n* We then use another **HTTP Request** to a `fal.ai` endpoint to get the duration of the audio file.\n* An **If** node checks to see if the duration was successfully retrieved.\n* Finally, a **Airtable** node creates a new record with the audio file's details, including the script, Google Drive link, and duration.\n\n\n### How to use it \ud83d\ude80\n* The **Form Trigger** node is a great way to start, but you can swap it out for a Webhook, a new row in a spreadsheet, or any other trigger that suits your needs.\n* You can easily customize the available voices and languages in the **Form Trigger** node.\n\n---\n\n### Requirements \ud83d\udccb\n* A **Google Cloud oAuth2 Client** with the Text-to-Speech API enabled.\n* A **Google Drive** account for storing the generated audio files.\n* A `fal.ai` account for the ffmpeg API to get the audio duration.\n* An **Airtable** account to log the generated audio files. You must create a new table with same fields as the Airtable node.\n\n---\n\n### Need Help? \ud83d\ude4b\nAsk in the [Forum](https://community.n8n.io/)!\n\n"
