A podcaster needs to morph a 4-minute interview clip from one speaker's voice to another's for a consistent series tone using only AI. The goal is a natural result that holds up at 48 kHz without new recordings.

Project Setup in the Dashboard

Open the workspace at /dashboard and load the source file. The clip runs 240 seconds at 44.1 kHz stereo. Select the voice cloning tool first so the system registers the target timbre before any generation starts. Upload a 45-second clean reference of the target speaker recorded at the same sample rate.

The platform creates a temporary voice profile that stays available for 24 hours. Confirm the profile matches the reference by playing back a 10-second test segment before moving forward.

Selecting the Base Audio and Reference

Return to the main audio page and choose Text to Speech to generate a neutral guide track. Input the exact transcript with timestamps every 15 seconds. This guide track locks the pacing so the morph stays synchronized.

Load the original interview as the source and the 45-second reference into Voice Cloning. Set the strength slider to 0.85 for a balance between fidelity and natural variation. The system processes the first 60 seconds in 22 seconds on average.

Running the Morph Generation

Trigger the conversion. The job consumes 3.5 credits for the full 4 minutes. Output arrives as a 48 kHz WAV file. Listen to the section between 1:45 and 2:10 where the original speaker laughs; the morphed version should retain the same timing and pitch contour.

If the laugh segment sounds flattened, return to the profile settings and lower strength to 0.78, then re-run only that 25-second slice.

Adding Lip Sync and Final Polish

Export the morphed audio and drop it into Lip Sync Video if a video version exists. The tool aligns mouth movements to the new voice at 24 fps. Check the 3:05 mark where the speaker says a plosive-heavy phrase; alignment error should stay under one frame.

For background elements, generate a matching music bed with Music Generation at -18 dB. Blend the bed under the morphed voice so the final mix peaks at -6 dBFS.

Quality Verification Steps

Play the full file on three different devices: laptop speakers, phone earbuds, and studio monitors. Note any sibilance spikes above 8 kHz. If present, apply a gentle 3 dB cut at 7.5 kHz using the built-in EQ before export.

Compare the morphed file against the original reference using a 10-second overlap test. The timbre match should score above 92 percent on the platform's internal similarity meter.

Model Comparison Table

Tool/Model	Strength	Best for	Limit	Price/Credit
Flixly Voice Cloning	0.85 timbre match	4-minute narrative clips	10-minute max per job	3.5 credits
Gemini 3.1 Flash TTS	0.79 prosody accuracy	Quick guide tracks	3-minute segments	2 credits
ElevenLabs Alternative	0.88 emotion range	Character dialogue	5-minute daily free tier	4 credits
Seedance 2.0 Audio	0.81 timing sync	Video-aligned morphs	2-minute real-time limit	2.5 credits

The table shows Flixly Voice Cloning leads on longer clips while Gemini 3.1 Flash TTS wins on speed for short guide tracks.

When to Use Which

Choose Flixly Voice Cloning for projects that need the full 4-minute consistency shown in the example. Switch to Gemini 3.1 Flash TTS when you only need the first minute as a timing reference. Test both on a 30-second sample before committing credits to the complete file.

After verification, download the final 48 kHz WAV and drop it back into the series workflow. Repeat the same steps on the next episode with the same saved voice profile at Voice Cloning.
