The client focuses on custom software development, primarily for business and commercial applications. Their goal is to provide simple, effective solutions that maximize their customer’ business potential. All of their commitment to pioneering new solutions allows them to deliver value to their customers.
Mindy Support’s team increased the quality of the client’s dataset by accurately annotating an audio dataset consisting of more than 10,000 entries. Our expertise in audio annotation techniques enabled to handle diverse types of audio data with proficiency and attention to detail. By leveraging advanced tools and techniques, Mindy Support’s team optimized the annotation process, delivering results that enhanced the overall quality and usability of the client’s dataset.
There is a wide variety of noises and sounds that occur both indoors and outdoors, and the client’s tool is needed to recognize all of them. They had a sizable dataset of 10,000 audio files consisting of sounds, and they needed a data annotation provider to classify whether all the sounds occurred indoors, outside, in a car, etc. Additional categories included pleasantness, eventfulness, calmness, excitement, comfort and safety, privacy and control, loudness, clarity and quality of sounds, spaciousness, human occupancy, and categorization of the content into dominant categories.
Data annotators were required to mark their answers for each question based on their perception of the audio recording since time was of the essence, all the files needed to be annotated in 4 months.
