Everything you need
to process voice data.

Upload audio. Get structured transcripts. Run your own AI prompts against them. Or use our LLM API directly.

Transcription API

Upload audio files via REST API. Get back speaker-diarized transcripts with word-level timestamps in JSON, plain text, CSV, or SRT.

from $0.30/hr

AI Analysis Engine

Bring your own prompts. We execute them against your transcripts using frontier-class LLMs. Compliance, sentiment, QA scoring — you define it.

How it works

Three steps.
No infrastructure required.

Upload your audio

Send any audio file — WAV, MP3, OGG, FLAC. We auto-detect stereo channels and language. Files up to 4 hours supported.

Get diarized transcripts

Receive speaker-labeled segments with precise timestamps. Our pipeline automatically identifies who said what, even in noisy recordings.

Run AI analysis

Send your own prompt templates. We run them against the transcript and return structured JSON. Build any workflow — compliance, coaching, summarization.

Developer experience

One API call. That's it.

Standard REST API. Upload a file, get a transcript. No SDKs required — works with cURL, Python, Node, anything.

python
import requests

response = requests.post(
    "https://api.voxparse.com/v1/transcribe",
    headers={"Authorization": "Bearer vox_sk_..."},
    files={"file": open("call_recording.wav", "rb")},
    data={
        "language": "en",
        "diarize": "true",
        "output_format": "json",
    },
)

transcript = response.json()
for segment in transcript["segments"]:
    print(f"[{segment['start']:.1f}s] {segment['speaker']}: {segment['text']}")
