Synthesizer V is a singing voice synthesizer. A musician enters notes in a piano roll, types lyrics under each note, and the software sings them in a chosen voice. Parameters control pitch, vibrato, breathiness, and timing, so a producer can shape the performance rather than accept a flat robotic output.
The AI voice databases are the main attraction. They are trained on real singers and sound more natural than older concatenative systems, and some support several languages with a single voice. Vocal modes change the style, such as a softer or more intense delivery. Synthesizer V runs as a standalone editor or as a plugin in digital audio workstations, and a free version offers limited features.
Voice databases are sold separately by the developer and partner studios, and licensing terms vary by voice. Results still take editing to sound convincing. Alternatives include Vocaloid, ACE Studio, Emvoice, Eleven Labs music tools, and UTAU as a free option. Synthesizer V suits producers who want synthetic vocals under their control.
