Code-Shift (Native European Spanish Speakers) Audio Recording (Dual-Channel)

Code-Shift (Native European Spanish Speakers) Audio Recording (Dual-Channel)
Recording Approach

We will deliver natural bilingual conversations in a contact-center (agent–customer) format with strict adherence to code-switching requirements.

Audio Format

* Dual-channel WAV (Agent / Customer separated)
* Native 8kHz and 16kHz recordings (50/50 split)
* Single recording per conversation with clear channel separation

Code-Switching Implementation

We support both required patterns:

Type 1: Bilingual Agent–Customer Interaction**

* Agent: 100% secondary language(English)
* Customer: 100% primary (European Spanish) language
* ~50% code-switching at conversation level
* Natural conversational flow (no forced switching)
* Single audio + single transcription with language tags

Conversation Design

* Duration: 5–30 minutes (avg. ~10 minutes per conversation)
* Multi-turn, real-world interaction style
* Context-driven switching (clarifications, technical terms, etc.)
* Natural tone, pauses, and conversational dynamics

Speaker & Resource Standards

* 80–90% native speakers for primary language
* Proficient bilingual speakers for secondary language
* Max 30 minutes recording per speaker (~6 conversations)
* Balanced and scalable speaker pool

Audio Quality Standards

We strictly ensure:

* Minimum 25 dB signal-to-noise ratio
* No background noise, echo, or distortion
* Consistent volume and clarity
* Natural delivery (not scripted reading)
* No AI-generated or synthetic audio

Quality Assurance & Rework

* Internal multi-level QA for audio and transcription
* Code-switching ratio and naturalness validation
* Acceptance target: ≥95% pass rate
* Rework handled within the same milestone if required

We ensure:

* Consistent quality across all language pairs
* Scalable execution for large volumes
* Reliable communication and milestone-based delivery

We’re ready to start with a pilot batch and scale based on your requirements.
