About This Tool

The tool converts audio into a structured JSON transcript with optional time-aligned tokens and speaker labels. It supports multiple languages, handles noisy audio, and exports a consistent schema suitable for ingestion by analytics, search, and BI pipelines.
The core process includes audio ingestion, ASR decoding, time-alignment, optional diarization, and optional punctuation restoration, all emitting a stable JSON schema with segments and word-level data.
Users can tailor the output to include per-word timestamps, speaker labels, and confidence scores, enabling precise downstream processing, indexing, and auditing. This is beneficial for developers embedding transcription in apps, data scientists building corpora, and compliance teams validating media archives. The tool emphasizes deterministic structure, predictable field names, and a schema that can be versioned and evolved without breaking downstream jobs.
Common use cases include meeting and podcast transcription, customer call analysis, media asset tagging, and searchable archives. Unique value lies in configurable fields, robust language handling, and optional diarization that remains stable across runs, reducing post-processing overhead and integration time.

How to Use

  1. Provide inputs: upload or provide a URL to the audio_file, select language, and choose required output details.
  2. Configure options: enable diarization, word-level data, and timestamps as needed.
  3. Run conversion: initiate the transform and monitor progress.
  4. Retrieve outputs: download the JSON payload or fetch via API.
  5. Validate and integrate: verify structure and feed into downstream pipelines or analytics tools.

Frequently Asked Questions

Find Quick Answers

What input formats are supported?
We support common formats such as WAV, MP3, FLAC, and OGG. Large files may be processed in chunks or via batch mode depending on plan and limits.
Can it identify multiple speakers?
Yes. Diarization assigns segments to individual speakers when enabled, producing speaker labels within the transcript and aligned segments.
Can I customize vocabulary?
Yes. You can provide a custom vocabulary or domain terms to improve recognition accuracy for specific fields or jargon.
Is this real-time transcription?
The tool is designed for batch processing and streaming options where available. Real-time, low-latency transcription is not guaranteed in all plans.
What output schema is produced?
The default schema includes transcripts, segments with start_time and end_time, optional speaker, and a words array with text, times, and confidence scores.
