Use case · Arabic audiobooks
Produce Arabic audiobooks at studio quality.
Audiobook narration is the long-form test for any voice AI. Hakim Faseeh v2 was built for hours-long coherence across 15 Arabic varieties: MSA for the formal canon, dialects for contemporary fiction, non-verbal tags for sighs and pauses that bring fiction to life, and voice cloning for series where the same narrator carries every book. Batch API renders an 8-hour novel in under an hour. Outputs ACX-ready for Audible, Storytel, plus regional Arabic distributors.
Three steps from manuscript to master
Bring your manuscript
EPUB, plain text, or chapter-split markdown. Hakim accepts manuscripts up to 500,000 characters per batch (one full novel). Chapter markers are preserved in the output CSV so your editor or distributor can split the master into per-chapter audio for streaming platforms.
Pick a narrator and dialect
Filter the catalogue by dialect (MSA for the formal canon; Egyptian, Khaleeji, Levantine, Maghrebi for contemporary fiction), gender, age, and narrative style (warm storyteller, dramatic, conversational, news-formal). Or clone the narrator's voice from a 10-second sample for a series where consistency matters more than catalogue choice.
Render in batch with chapter timestamps
Submit the manuscript via the batch endpoint; receive a webhook when rendering is done. Per-chapter audio files plus a master mixdown plus a CSV of chapter timestamps land in your S3 bucket. Pass the timestamps to ACX, Audible, Storytel, or your regional distributor's ingest pipeline.
Built for audiobook production
Long-form voice coherence
Hakim Faseeh v2 was built for novel-length output. The voice doesn't drift, doesn't develop synthetic-edge fatigue at hour four, and doesn't lose its emotional register between chapter one and chapter eighteen. The same narrator voice carries an entire trilogy without per-book retraining.
Dialect choice tuned for genre
MSA for classical literature, religious texts, and formal nonfiction. Egyptian or Levantine for contemporary fiction where colloquial dialogue carries the prose. Khaleeji for Gulf-set thrillers and family sagas. Maghrebi for Maghrebi authors. Pick the variety that matches the book's voice, not the platform's defaults.
Voice cloning for series
A series benefits from a single narrator across every volume. Clone the narrator's voice from a 10-second consented sample; subsequent books use the same voice with no quality drift. Watermarked, audit-trailed, and locked to your account so the cloned voice can't leak to a competing publisher.
ACX-compliant output
Outputs land at the spec ACX (Audible's distribution platform) actually accepts: 192 kbps CBR MP3, 44.1 kHz, mono, RMS between -23 and -18 dB, peak below -3 dB, room tone < -60 dB. WAV at 48 kHz for masters, FLAC for archive. The same render produces every format in one batch.

}'Built for these audiobook workflows
Independent authors and small presses
Self-publishing authors producing the audiobook version of their novel without booking a studio. The free tier covers a chapter of evaluation; the paid tier renders a full novel for under USD 100 in compute. Distribute on ACX, Storytel, or sell direct.
Trade publishers with a regional Arabic catalogue
Trade publishers who need to produce 50-100 audiobooks per year across MSA and dialect markets. The dialect catalogue lets one workflow address Egyptian, Khaleeji, Levantine, and Maghrebi audiences without booking four separate studios. Per-narrator voice cloning keeps series consistent.
Religious and educational publishing
Quranic recitations are NOT a Hakim use case (we don't synthesise religious recitations on principle). But Islamic studies, Arabic literature, and educational nonfiction in MSA are core to our audiobook surface. The voice catalogue includes formal-register narrators tuned for nonfiction tone.
Public-domain Arabic literature
Producing audiobook editions of Arabic classics whose copyright has expired. Naguib Mahfouz, Mahmoud Darwish, classical poetry, the Arabian Nights. The Faseeh v2 storyteller voices carry the prose; MSA + Egyptian narrators are the highest-leverage picks for canonical works.
