Voice Conversion

At OnlinExperiment, we specialize in sophisticated voice conversion, offering an array of tools that enable precise control over vocal attributes such as duration, fundamental frequency (f0), and vocal tract length (VTL). Our services are available both online and on-site, catering to diverse research needs in speech sciences and related fields.

Our platform utilizes a python server for real-time voice transformation, which allows researchers to modify pitch, formant frequencies, and the duration of speech signals interactively. This capability is crucial for experiments that require detailed study of speech perception and speaker characteristics across different scenarios.

We also integrate a vocoder, a powerful tool for the analysis and synthesis of speech signals. This technology supports high-quality voice conversion by facilitating pitch extraction, speech parameterization, and the synthesis of altered vocal outputs. It is invaluable for creating nuanced manipulations based on vocal tract length and other significant speech parameters.

To complement our voice manipulation technologies, we provide robust scripting solutions using Python, with libraries like NumPy and SciPy for data handling and algorithm implementation. Visualizations and interactive manipulations are enhanced with Matplotlib and Seaborn, allowing researchers to see and interact with the changes in real time.

Whether conducting on-site experiments or accessing our tools online, researchers can leverage our advanced voice manipulation capabilities to explore and understand speech dynamics more comprehensively. OnlinExperiment is dedicated to advancing the frontiers of voice research by delivering cutting-edge tools that enable innovative studies and practical applications in voice manipulation.
