Long term for a streamlined data annotation workflow
What is your pricing?
We calculate according to how much time is spent on your object annotation. That’s why the pilot project is also valuable for us – we get to calculate the expenses
When can I start the free pilot?
As soon as we clarify details on your dataset. You’ll get a reply within this or the next work day.
Do you work with our labeling tools?
Absolutely! We’re flexible with any tools you want us to work in.
How can I trust you with my confidential data?
We earned several data compliance certificates to prove our dedication to data security:
PCI DSS Level 1
ISO:27001

CCPA
After we sign the NDA, we make sure to anonymize your data for our employees to prevent any data leaks.
How do I annotate audio files?
To annotate audio files, you use software tools to tag key elements such as speech segments, sounds, or speaker changes. This can involve marking specific time stamps, labeling words, or identifying background sounds. If you want to avoid the hassle, our team at Label Your Data can handle the entire process, ensuring accuracy even in noisy or complex audio files.
What is voice annotation?
Voice annotation is the process of labeling specific parts of a voice recording, such as identifying speakers, transcribing spoken words, or tagging emotions. It’s commonly used for training AI models in speech recognition, customer service analytics, and virtual assistants. At Label Your Data, we deliver accurate and efficient voice annotation tailored to your project needs.
What is the tool used for audio annotation?
At Label Your Data, we use our custom-built tools designed for precise and efficient audio annotation. If you have a preferred tool, our team is flexible and can work with your chosen platform. We ensure a smooth annotation workflow regardless of the tool used.
