For a deep-sounding music vocal, Voice Morph is the clearest match: its site explicitly describes lowering a voice for a deeper tone. For more control over musical vocal conversion, Altered Studio, Kits AI, Audimee, Applio, IK Multimedia ReSing, and RVC WebUI are relevant alternatives, but their supplied descriptions do not confirm a specific deep-voice preset or result. Xiaomi, Redmi, and POCO users should check each vendor’s current device and browser requirements before choosing; phone compatibility is not established for most of these options.
What To Check Before Converting A Vocal
A deep voice conversion changes the vocal identity while the performance remains the source. For a song, start with a clean vocal recording and decide whether you want a subtle lower register or a distinctly bass-heavy character. Then check that the tool accepts your recording and offers a target voice suitable for that sound. Do not assume a general voice converter includes a deep preset: among the tools below, that specific capability is established only for Voice Morph.

Recommended Free Tools
For a practical workflow, use a short phrase with both low and high notes, convert it, and listen for whether the words and pitch movement still suit the song. If the vendor does not document this workflow or a target voice, check its current product information before uploading a full track. No product here has a verified Xiaomi, Redmi, or POCO app listing in the supplied details.

1. Voice Morph
Voice Morph is the strongest fit when the brief specifically calls for a deeper voice: its own description says users can lower a voice, and its preset library includes deep bass voices. The free plan allows three conversions per day and clips up to 30 seconds; converted audio is provided as WAV. The Pro plan starts at $3 per month and adds custom voice upload, a studio mixer, and HD 48 kHz export.

For a song demo, record a short vocal phrase in the browser, try a listed deep preset, and compare the result against the original before committing to a longer section. The available facts do not establish a particular music genre, vocal range, or Xiaomi, Redmi, or POCO app, so check the vendor’s site for those specifics. Voice Morph says its designed voices are original and do not imitate real people; if you upload a custom voice sample, use one you own or have permission to use and check the platform’s terms.
2. Altered Studio
Altered Studio supports speech-to-speech and performance-to-performance voice morphing, which makes it a plausible choice when preserving a singer’s delivery matters. Its described features do not establish a deep-voice target, so confirm that the available voices can produce the tone you need. The free plan limits voice morphing to three minutes per month; paid plans start at $30 per month with annual billing, and a seven-day trial is listed.
For a musical test, use a short recorded line with the timing and inflection you want to keep, then check the converted voice against the backing track. Real-time transformation is documented in a related interface, and platform availability includes web, Windows, macOS, and major creator platforms. Device requirements for Xiaomi, Redmi, and POCO phones are not stated. Altered describes voice replication; use only a voice you own or have the speaker’s consent to replicate, and check its terms before sharing or releasing converted audio.

3. Kits AI
Kits AI combines vocal conversion with voice cloning, blending, separation, and mastering. That makes it useful for a vocal-production workflow, though the available information does not confirm a deep-voice preset. Check the voice options before building a track around a low vocal. Its free plan includes 15 conversion minutes and no download minutes; paid plans start at $10 per month.
A restrained workflow is to convert one exposed vocal phrase first, then decide whether its timbre fits the song before processing more material. Kits says its model voices are ethically licensed and securely sourced, and that artist models use revenue sharing; it also notes that artist-model outputs may require approval for commercial release. Use a voice you have permission to use, and check the relevant model and platform terms for your intended release.
4. Audimee
Audimee offers vocal conversion, isolation, pitch editing, and harmony tools in a web-based workflow. The supplied details do not establish deep-voice targets, so inspect its voice choices before relying on it for a bass-heavy sound. Its introductory free allowance is 15 minutes and does not reset; paid plans start at $9 per month, with conversion-time caps on Starter and Pro.

Audimee describes its voices as royalty-free and supports training your own voices; use only recordings you have permission to upload and check its terms for the voice and release you plan to use.
5. Applio
Applio is a free, open-source voice conversion suite for real-time and uploaded-audio conversion, custom model training, voice blending, and batch inference. Those functions can suit a creator who wants to work with musical voice models, but the supplied information does not confirm a deep-voice model or a phone workflow. Applio lists Windows, macOS, Linux, Colab, and Kaggle support; check its current setup instructions for your device.
One concrete approach is to convert a short vocal file with a model you are entitled to use, then assess the tone in the musical context before processing a full performance. Applio says it may be used, modified, and redistributed for personal projects, research, or commercial work. That statement does not establish rights to a particular source voice or model: get consent for a person’s voice and review the terms for any model you use.

6. IK Multimedia ReSing

Paid plans start at $129.99 one-time.

Pick the symptom - the matching free tool is one click away.
For a lower vocal idea, a producer could create a model from an authorized voice and adjust timbre and transpose in a short passage, then check the result in the arrangement. ReSing describes personal use or leasing a modeled voice for profit, but that does not settle rights for every source voice or use. Get the speaker’s consent and check the product terms for the model and planned release.
7. RVC WebUI
RVC WebUI is a free, self-hosted toolkit for technical users. It supports real-time and offline conversion, training, model fusion, pitch controls, retrieval, and batch processing, with audio export in WAV, FLAC, MP3, and M4A.

A musical workflow could use a locally trained model on a short vocal excerpt, then adjust pitch controls and compare the converted line with the original. That is a suggested use of its documented functions, not a guarantee of a deep result. The project’s supplied description discusses its base model, but it does not establish permission to imitate a particular person. Use a consenting speaker’s voice or a model you have rights to use, and check the project and model terms.

Before converting or sharing a vocal, make sure the source recording and target voice are ones you are allowed to use. A service’s statements about its own presets or licensed models do not automatically cover a voice sample you upload or a model you import. Check the current vendor terms for your intended use, especially if you plan to publish or monetize the result.
