Transcribe & translate audio between languages with OpenAI Whisper, GPT-4, and S3 storage.
Receives an audio file via webhook and transcribes it using OpenAI Whisper. Translates the transcript to the target language with GPT-4 and structures it for natural speech. Generates translated speech and stores both the transcript and audio in S3, returning a shareable URL.
A concise, end-to-end capability set.
Ingests audio via webhook
Transcribes audio with Whisper
Detects source language when not specified
Translates transcript into target language
Generates speech from translated text
Stores transcript and audio in S3 and returns access URLs
Before, teams juggle multiple tools for transcription, translation, and voice generation, leading to delays and inconsistent outputs. After, a single AI agent handles ingestion, transcription, translation, speech synthesis, and storage, delivering ready-to-share outputs.
A simple 3-step flow from ingestion to delivery.
Receive the audio via webhook and transcribe using Whisper.
Translate the transcript to the target language with GPT-4 and format for speech synthesis.
Generate translated speech, store transcript and audio in S3, and return shareable URLs.
A realistic scenario showing end-to-end usage.
A 12-minute English podcast is posted to the webhook. The agent transcribes it with Whisper, translates the transcript to Spanish using GPT-4, synthesizes natural Spanish speech, and stores both the transcript and the new audio file in S3. The system returns a transcript and a URL to the translated Spanish audio within seconds.

Answers to common questions about this AI agent.
We support common formats like MP3 and WAV. The AI agent handles ingestion via webhook and validates file type before processing. Quality checks ensure the transcript and translation stay aligned with the audio. Large files may require chunking or staged processing to maintain performance. You can configure size limits and format checks as part of the setup.
Accuracy depends on audio quality, language, and model capabilities. Whisper offers strong transcription for clear speech, while GPT-4 translates with contextual awareness. Post-processing steps can include spell-checking and consistency checks to improve reliability. For critical use cases, human review can be embedded in the workflow.
Yes. The AI agent can detect source language when not specified and select the correct translation path. You can enable or disable automatic language detection in configuration. Detection runs before translation to ensure the best language model and vocabulary. If languages are ambiguous, you can provide explicit source and target languages.
Security is addressed through webhook authentication, access controls on the S3 bucket, and optional rate limiting. Transcripts and audio files are stored securely with access policies. You can implement encryption at rest and in transit, and audit logs can be enabled in your environment. The agent should not expose data beyond configured permissions.
Yes. You can adjust voice speed, pitch, and select different voice profiles where supported. These settings can be configured per language or per translation task. The customization is applied during speech synthesis to ensure natural-sounding output. You can save presets for recurring projects.
The AI agent returns a transcript, a translated audio URL, and the translated audio file. Outputs are stored in the configured S3 bucket and URL is provided in the response. You can configure additional delivery methods, such as API callbacks or webhook responses. Access controls and expiry policies can be set on generated URLs.
Yes. You can set file size limits and rate limits as part of the webhook/configuration. Large files may require chunked processing or staged delivery. The AI agent enforces limits to maintain performance and privacy. For high-volume workloads, batch processing or queueing can prevent bottlenecks.
