### Hardware Setup
- **Throat Microphone**: [CodeRed Assault MOD Tactical Throat Mic Headset](https://coderedheadsets.com/assault-mod-tactical-throat-mic-headset/)
- Uses standard 3.5mm audio jack
- Direct connection to MacBook Air's 3.5mm port
- Note: Many USB-C to 3.5mm microphone adapters are not compatible with throat microphones (CIAA/TRRS)
### Dataset Summary
A high-quality dataset of throat microphone (laryngophone) recordings specifically designed for fine-tuning Whisper and other speech recognition models. The dataset consists of 605 carefully selected English sentences recorded using a throat microphone, which captures speech through vibrations in the throat rather than air-conducted sound.
This dataset is particularly valuable for:
- Training ASR models for noisy environments
- Adapting speech recognition to throat microphone input
- Developing robust voice activity detection
- Research in alternative speech input methods
### Dataset Statistics
- **Total Recordings:** 605
- **Total Duration:** 100.4 minutes
- **Average Duration:** 10.0 seconds (median: 10.0s)
- **Duration Range:** 5.9s - 11.0s
- **Standard Deviation:** 0.3s
Duration Distribution:
- <6s: 0.2% (1 recording)
- 6-8s: 0.7% (4 recordings)
- 8-10s: 98.7% (597 recordings)
- 10-12s: 0.5% (3 recordings)
- 12s or greater: 0%
### Linguistic Characteristics

### Supported Tasks
This dataset is suitable for:
- **Automatic Speech Recognition (ASR)**: Training models to transcribe throat microphone audio
- **Speech-to-Text**: Converting throat microphone recordings to text
- **Voice Activity Detection**: Detecting speech in throat microphone signals
- **Domain Adaptation**: Adapting existing ASR models to throat microphone input
### Languages
The dataset contains English-language recordings only, with:
- Standard American English pronunciation
- Academic and technical vocabulary
- Complex sentence structures
- High-quality transcriptions
## Dataset Structure
### Data Instances
Each instance in the dataset contains:
```python
{
'audio': {
'path': str, # Path to the audio file
'array': np.array, # The audio signal array
'sampling_rate': int # 16000 (16kHz)
},
'text': str, # The transcription
'duration': float # Length in seconds
}
```
### Audio Quality
All recordings meet strict quality requirements:
- Sample Rate: 16kHz mono
- Duration: Typically 8-10 seconds (98.7% of recordings)
- Audio Levels: -50dB to 0dB
- Signal-to-Noise Ratio: >10dB
- Silence Ratio: <30%
- Clean, professional recording environment
### Data Fields
- `audio`: Audio file in WAV format (16kHz mono)
- `text`: String containing the transcription
- `duration`: Float value representing duration in seconds
### Data Splits
The dataset is provided as a single training split.
## Dataset Creation
### Curation Rationale
This dataset was created to address the lack of high-quality throat microphone data for training speech recognition models. Throat microphones are particularly useful in noisy environments as they capture speech directly through throat vibrations.
### Source Data
#### Initial Data Collection and Normalization
Sentences were carefully selected to ensure:
- Complexity suitable for model training (9-18 words)
- Proper grammar and punctuation
- Mix of statement types
- Natural language patterns
- Varied vocabulary
- Balanced phonetic content
### Annotations
The annotations (transcriptions) are the original sentences used for recording, ensuring 100% accuracy.
## Considerations for Using the Data
### Social Impact of Dataset
This dataset can help improve speech recognition in:
- High-noise environments
- Military and emergency services communications
- Industrial settings
- Assistive technology for voice disorders
### Discussion of Biases
The dataset:
- Contains only English language
- Uses standard English pronunciation
- May not represent all accents or dialects
- Recorded by a limited number of speakers
### Other Known Limitations
- Limited to throat microphone recordings
- May not generalize well to regular microphone input
- Optimized for 8-10 second utterances
