Digital Voice Transmission Using Software-Defined Radio

With the growing demand for flexible and cost-effective digital voice communication, this paper presents an SDR-based system using GNU Radio and PlutoSDR. The system converts voice signals into digital form and transmits them over radio frequencies, demonstrating reliable FMvoice transmission. Additionally, it incorporates male-female voice generation and gender-based voice characterization, enhancing signal analysis. This work highlights SDR's potential for scalable and efficient wireless communication systems.
