|
|
import { createClient } from "@deepgram/sdk";
|
|
import { logger, task } from "@trigger.dev/sdk";
|
|
|
|
// Initialize the Deepgram client, using your Deepgram API key (you can find this in your Deepgram account settings).
|
|
const deepgram = createClient(process.env.DEEPGRAM_SECRET_KEY);
|
|
|
|
export const deepgramTranscription = task({
|
|
id: "deepgram-transcribe-audio",
|
|
run: async (payload: { audioUrl: string }) => {
|
|
const { audioUrl } = payload;
|
|
|
|
logger.log("Transcribing audio from URL", { audioUrl });

|
const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
|
|
{
|
|
url: audioUrl,
|
|
},
|
|
{
|
|
model: "nova-2", // Use the Nova 2 model for the transcription
|
|
smart_format: true, // Automatically format transcriptions to improve readability

|
|
}
|
|
);
|
|
|
|
if (error) {
|
|
logger.error("Failed to transcribe audio", { error });

|
}
|
|
|
|
console.dir(result, { depth: null });
|
|
|
|
// Extract the transcription from the result
