Convert a recording with Ilaria RVC
Voice conversion starts with a performance. The output usually follows the source words, timing, articulation, and pitch contour while changing the sound of the voice. Decisions about delivery still start with the original recording. For a sung cover, plan to convert an isolated lead vocal and mix the converted vocal with the instrumental afterward.
Make a baseline conversion
- Open Ilaria RVC and import the inference model you want to use. An optional index belongs with the checkpoint it was built for. If an imported voice is absent from the selector, see RVC models and files.
- Open Single Inference, choose the voice, and drag in a short recording you can recognize by ear. A phrase with a pause, several consonants, and a longer vowel makes a useful reference.
- Set Pitch to zero and Index Ratio to zero. Match the content embedder to the one used in training when the model author provides it. Start with the app's default pitch extractor and leave optional audio processing off.
- Convert the file and check the output. Use the waveform player to revisit the same phrase, then save a WAV or FLAC copy as your baseline.
- Compare the original and the converted clip at similar playback levels. Note the first audible problem and use Pitch and audio quality to decide what to change.
Current Ilaria RVC releases automatically look for a matching index when you select a voice. Selecting an index and giving it influence are separate actions. A loaded index contributes only when Index Ratio is above zero. Older builds may show a different layout or ask you to select the index manually. Ilaria RVC project README
Choose a source that fits the job
If a separated vocal still contains loud cymbals or another singer, compare it with a cleaner take or separation. Those sounds reach the conversion engine along with the intended voice. Keep breaths and word endings where they matter to the performance.
Convert a batch
Open Batch Inference after a single file produces a usable result. Group files that need the same model, pitch, and processing profile. Run one representative file from each group and save to a separate output location so you can compare results safely.
For a long song, audition a section with exposed high or low notes before converting the whole file. Split Audio can help with long recordings or memory limitations. Listen across segment joins and pauses after the run. If a version of the app exposes a console or conversion log, use it to identify any failed items and retry those files separately.

Convert generated speech
In a release with the TTS workspace, supply text or a UTF-8 text file. Current Ilaria RVC releases offer Microsoft Edge online voices and installed Windows voices for offline TTS. Pick a source voice in the language of the script, listen for pronunciation and pauses, and then apply the RVC model to that generated recording. If the first stage reads a name incorrectly, fix the text or change the TTS voice first. RVC will generally carry those source pronunciation choices through.
When privacy or an unreliable connection matters, select an installed Windows voice and check that it works with your text before starting a long job. The Edge option requires a network connection. Ilaria RVC TTS features
Save the conversion and your settings
- Keep an unprocessed WAV or FLAC master before adding compression, reverb, or limiting.
- For music, align the converted vocal against the original, check its timing at consonants, and listen to both solo and in the mix before exporting.
- Save your settings alongside the result. Include the source file, model and index versions, speaker ID if applicable, embedder, pitch extractor, pitch shift, index ratio, processing, and output format.
- When a model is missing or inference fails before producing audio, start with Troubleshooting. For microphone conversion, see Real-time voice conversion.
