Frequently Asked Questions
What audio formats do you deliver?
We deliver WAV (PCM, 48kHz, 16-bit) by default. FLAC, MP3, and OGG formats are available upon request. All deliveries include JSON metadata with speaker demographics, timestamps, and transcriptions.
How do you ensure dialect accuracy?
All speakers undergo linguistic validation by native linguists. We verify regional birthplace, primary language exposure, and conduct accent verification tests before recording begins.
What are your minimum project sizes?
Minimum project size is 5 hours of recorded audio per language. For pilot projects or demos, we can accommodate smaller scopes (1-2 hours) with adjusted pricing.
Can you record custom scripts?
Yes. You can provide custom scripts for prompts, dialogues, audiobooks, or training phrases. We'll review for linguistic naturalness and suggest optimizations if needed.
What licensing options are available?
Standard license includes unlimited commercial AI training use, internal distribution, and model deployment. Extended licenses cover data resale, public dataset release, and multi-entity sublicensing.
