AI Sentence Catch

Why It Exists

Users often need to quickly capture spoken information but struggle with traditional note-taking while engaged in conversation. AI Sentence Catch provides a seamless way to capture and organize spoken words as text.

How It Works

AI Sentence Catch uses OnePlus AI's on-device speech recognition models to capture spoken words in real-time and convert them to editable text. The feature is designed for quickly capturing ideas, quotes, or notes during conversations, meetings, or lectures. It organizes captured sentences with timestamps and can identify speakers if multiple people are talking.

Everyday Use Cases

• Capture meeting notes and action items
• Record interesting quotes during a lecture
• Save ideas during brainstorming sessions
• Transcribe interviews
• Create searchable records of conversations

User Workflow

• Open AI Sentence Catch in the Notes app on a OnePlus device
• Start recording
• Speak naturally
• AI transcribes speech to text in real-time
• Review and edit the transcribed text
• Save or share the notes

AI Processing Flow

On-device speech recognition model processes audio using the NPU, converts speech to text, and organizes sentences with timestamps. Speaker diarization may use cloud processing for complex scenarios.

Inputs / Outputs

Inputs:

• Audio recording
• Speech audio
• Speaker separation data
• Timestamps
• Language settings

Outputs:

• Transcribed text
• Timestamped sentences
• Speaker labels
• Editable text
• Searchable notes

Known Limitations

• Requires OnePlus devices with NPU
• Accuracy varies with audio quality and accents
• May struggle with background noise or multiple speakers

Unsupported Scenarios

• Does not work on devices without NPU
• May fail in very noisy environments or with strong accents not in training data

Performance Notes

Real-time transcription has minimal latency. Post-processing and speaker identification may take 2-5 seconds. Best accuracy in quiet environments on devices with NPU.
