What components are included in a wake word dataset?
Speech Recognition
Wake Word
Dataset
A wake word dataset from FutureBeeAI includes:
- Wake word audio samples
- Follow-up command phrases
- Diverse speaker and environment recordings
- High-quality WAV files, transcripts, and rich metadata
- QA-verified annotations
This comprehensive structure ensures our datasets are robust and ready to enhance the performance of voice-activated AI technologies.
Wake Words + Command Phrases
Our datasets feature comprehensive audio collections of primary wake words like “Alexa,” “Hey Siri,” and “OK Google,” as well as brand-specific and device-specific triggers such as “Bixby” and “LG Smart.” Additionally, they include command phrases that follow wake words (e.g., “Hey Google, play music”) and standalone commands (e.g., “Turn on lights”).
Audio Standards & File Structure
We maintain strict standards for audio quality, providing files in 16 kHz, 16-bit, mono WAV format. Each dataset is paired with detailed transcription files in TXT or JSON formats, and a comprehensive metadata schema that captures speaker demographics, language, and recording environment.
Diverse Speaker & Environment Recordings
Our datasets ensure diversity by including recordings from a broad range of speakers across different accents, age groups, and genders. These recordings are made in various noise-controlled environments, simulating real-world conditions and enhancing model robustness.
Pre-processing & Annotation
Before inclusion, audio is subjected to:
- Noise filtering
- Normalization
- Silence trimming
Transcripts are annotated with phoneme-level alignment and timestamped segments, ensuring precise accuracy. Our in-house QA workflow validates these through a 2-layer review system, maintaining audio quality with less than 1% Word Error Rate (WER).
Data Augmentation & Balance
To bolster model robustness, we apply data augmentation techniques such as synthetic noise injection and speed/pitch variation. We also enforce balanced speaker quotas, ensuring representation across different demographics for enhanced model generalization.
Compliance & Privacy
All recordings comply with privacy regulations such as GDPR and CCPA. We manage consent meticulously and remove any personally identifiable information (PII), ensuring the integrity and security of our datasets.
Performance Metrics & Dataset Volume
Our internal QA ensures metadata accuracy exceeds 99%. Each Off-the-Shelf (OTS) dataset contains approximately 1,000–5,000 utterances per wake word, collected across more than 10 different environments, catering to multilingual needs.
Real-World Applications & Use Cases
FutureBeeAI's wake word datasets are vital for various applications, including smart home devices, automotive voice assistants, and mobile applications. These datasets drive high accuracy and efficiency in voice-activated systems, enhancing user experiences across industries.
