Image Annotation Services

With image annotation, we define and label each object in the picture, so that AI models can easily detect and locate them. We offer Image Annotation Outsourcing Services to train computer vision models.

  • Bounding Box Annotation

    Used for object recognition in a picture by enclosing it in a rectangular box and labelling it.

  • Polygon Annotation

    Distinguishing non-standard/irregularly shaped objects with free-form outlines and labelling.

  • Semantic Segmentation

    Pixel-level tagging of an image for providing detailed labelling of objects in an image.

audio-annot

Audio Annotation Services

Listed as one of the top Audio Annotation Companies, we create perfectly labelled datasets with our labeling expertize. Suitable for speech recognition systems, voice assistants, and audio-based AI technologies.

  • Speech-to-text transcription

    Conversion of speech notes/audio signals to editable text

  • Speaker Identification

    Separating and tagging each speaker’s voice into audio segments to improve AI response.

  • Emotion Detection

    To recognize speaking patterns and tonality to understand the tone, pitch and emotions in the audio.

  • Noise Tagging

    Labelling background sounds from audio recordings, so the AI assistant can filter and produce a clear and quality output.

Frequently Asked Questions

Data annotation is the process of categorizing and labelling various datasets to teach AI assistants. Images, texts, audio and video files can be marked for better understanding and improved response of DL and ML models.

Of course, it is cheaper. Data annotation is a time and resource-consuming work, needing dedicated and skilled staff to produce accurate outputs. Assigning an in-house team for this may incur a huge hiring cost and management overhead. Outsourcing data annotation specialists from a reputed firm like Velan helps you reduce costs and reduce workload.

The finished datasets are monitored and evaluated through strict quality assessment. We guarantee the timely delivery of 100% error-free, high-quality structured datasets for AI training.

Annotation experts help NLP models learn better by clearly labelling text data. They tag intent, meaning, and context so the model understands language accurately and responds relevantly.

The price of data annotation work depends on the type and size of the dataset. At Velan, we offer cost-effective services for all your data tagging needs. Connect with our team now to get a price estimation.
