Audio Annotation Services

We use state-of-the-art audio annotation tools along with manual methods for classifying and detecting sounds with high accuracy. We also employ a human annotation expert to review and validate the results of the annotated audio to ensure the annotations are accurate and consistent. Following the annotations, machine learning models are trained to recognize speech & sounds and detect acoustic events.

Our Audio Annotation Process

Sound Annotation or Labeling

Sound Annotation or Labeling

We identify and classify sounds like speech, background noise, and music using AI audio labeling tools and manual methods. We specialize in tagging sounds with accurate labels to enable users to search through audio recordings and locate sounds easily.

Through our sound labeling expertise, producers and editors can quickly find the sounds they require saving themselves both time and money.

Event Tracking

This involves using both software and human expertise to analyze and annotate audio recordings. The audio recordings are then segmented into events so that they can be identified quickly and accurately by users.

Audio recordings can be analyzed with annotations to track specific events, investigate suspicious or criminal activities, or monitor communication networks.

Speech-to-Text Transcription

Speech-to-Text Transcription

Audio annotation offers additional context and information for speech-to-text transcription by describing the audio. Factors like speaker’s gender, age, and accent, along with background noise levels are considered while processing speech or podcast annotations.

The speech-to-text system can better understand audio with an annotated transcription if the annotations are done properly.

Audio Classification

This involves assigning appropriate labels to audio recordings based on their content which may include descriptors like genre, artist, emotion, and sentiment. It is a manual process, but AI-powered audio labeling tools can automate the process. Data annotation experts should be employed for accurate audio classification since annotating audio is a labor-intensive task.
