WhatsApp Audio to Text Converter

The tool converts WhatsApp audio messages into readable text. It accepts audio inputs in common formats, detects language, and applies speech-to-text processing with punctuation and optional timestamps. Transcript timing and speaker labels can be enabled for multi-person chats. Outputs can be plain text or subtitle formats to integrate with logs.

Conceptually, audio streams are segmented, feature-extracted, and decoded by neural models trained on multilingual data; alignment ensures words map to timestamps. The system supports pt-BR and en-US and handles longer messages by chunking and reassembly.

The unique value lies in tight WhatsApp compatibility, optional diarization, and export formats. Core features include language detection, streaming or batched transcription, punctuation, timestamps, and multiple outputs.

Use cases include personal chat history, customer support threads, and compliance records. An example: a 60-second voice note yields transcript with 85–95% accuracy under good conditions.
