If voice cloning produces a poor result or fails entirely, the most common cause is the quality or length of the audio sample. This article covers the typical problems and how to fix them.
Cloning failed with an error
The audio file may be too short. Minimum is 10 seconds; 30+ seconds recommended.
The file format may not be supported. Use MP3, WAV, AAC or OGG.
The file may be too large (max 20 MB).
The audio may have no speech — silence, music only or noise.
Fix: re-record or upload a clean audio sample that meets the requirements. See Tips for the best voice clone quality.
The clone does not sound like me
Background noise: record in a quiet room with no music, TV or other voices
Too short: record at least 30-60 seconds of clean speech
Unnatural speech: speak at your natural pace, not too slowly or over-articulated
Phone recording: phone call recordings are compressed — use a dedicated voice recording app for better quality
The voice sounds robotic
A robotic sound usually means the model did not have enough clean audio to work with. Try:
Recording in a quieter location
Recording longer (60+ seconds)
Reading the reference text in the app — it is designed to capture voice characteristics efficiently
The clone sounds different in another language
Voice models are trained with specific language patterns. A voice cloned from Russian audio may sound different when generating English speech. For best results, record your sample in the language you plan to generate speech in.
