Off-the-Shelf Dual-Channel Speech Corpora

I need ready-made, professionally recorded conversational speech that I can license immediately for AI training. All material must be dual channel (each speaker isolated), feature spontaneous human dialogue, and come with accurate time-aligned transcriptions plus basic speaker metadata.

Languages and expected hours per language are as follows:
• Spanish – US (es-US): 220h
• French – Canada (fr-CA): 220h
• Arabic – UAE (ar-AE): 220h
• Italian (it-IT): 220h
• Thai (th-TH): 195h
• Turkish (tr-TR): 220h
• Hebrew (he-IL): 220h
• Dutch (nl-NL): 220h
• Greek (el-GR): 220h
• Vietnamese (vi-VN): 220h

The recordings should cover a healthy mix of customer service interactions, casual conversations, and technical support calls. Within those, I specifically want sessions that touch on Healthcare, Finance, Travel & Tourism, and everyday general topics so the dataset remains domain-diverse.

Key requirements
• Dual-channel WAV or FLAC with 8 kHz, 16-bit PCM (or higher)
• Human-generated speech only; no synthetic voices or read scripts
• Natural background noise acceptable as long as speech is clear
• Turn-level, verbatim transcription in UTF-8 with speaker labels and timestamps
• Documentation outlining collection methodology, consent, and demographics (age, gender, accent, mic type)

Acceptance criteria
1. Sample package (5-10 minutes) passes a quick audio quality and transcription accuracy check.
2. Full corpus delivery via secure download or shipped drive.
3. Metadata and licenses confirm worldwide, perpetual research & commercial use.

If you already have all or part of this inventory, let me know which languages, hours, and domains you can supply and your proposed delivery schedule.
