Audio Identification API

Skaldleita

Pronounced: SKAHLD-lay-tah  •  Old Norse for "Seek the Storyteller"

Identify audiobook narrators and books from audio clips.

Like Shazam, but for audiobooks. Upload a clip, and Skaldleita uses voice fingerprinting to identify the narrator — then matches the content to find the exact book.

Two Signals, One Answer

Voice fingerprinting meets content recognition

🎙️

Voice Fingerprint

256-dimensional voice embeddings identify narrators with over 90% accuracy. Each narrator's voice is as unique as a fingerprint.

📚

Narrator Catalog

Voice match narrows your search from millions of books to a narrator's catalog of 50-400 titles. Dramatically reduces false positives.

🔍

Content Matching

GPU-accelerated transcription extracts the spoken text. Combined with narrator identity, we pinpoint the exact book.

Fast Results

Narrator identification in under 2 seconds. Full book identification including transcription in under 30 seconds.

🎧

Any Format

Works with MP3, M4B, M4A, WAV, and more. Just upload 30-90 seconds of clear narration.

🌐

Simple API

RESTful API with JSON responses. One endpoint, one file upload, instant results. Free tier available.

How It Works

Three steps to identification

1

Upload Audio

Send 30-90 seconds of audiobook narration. Skip intros like "This is Audible" — start where the actual story begins.

2

Voice Analysis

We extract a 256-dimensional voice fingerprint and compare it against our database of narrator profiles. The match narrows down possibilities dramatically.

3

Book Identification

Using the narrator match plus transcribed content, we search our database and the web to identify the exact book, author, and series.
