Changing voice on a smartphone is often a necessity when the standard robotic tone is no longer comfortable for the user or annoys the user with prolonged use of the navigator. Owners of Xiaomi, Redmi and Poco devices can face a situation where the built-in voice engine sounds monotonous or unnatural, which is especially noticeable when reading e-books or articles aloud. Fortunately, the Android operating system provides flexible tools to replace this component without the need to obtain superuser rights.
The process of replacing voice does not require deep technical knowledge, but it involves understanding the difference between a speech synthesizer system and voice packets for specific applications. Speech synthesizer is the basic mechanism that converts text to audio, and it is the replacement that we will consider first. Often users confuse the media volume settings with the engine settings, which leads to mistaken conclusions about the impossibility of changing.
In this article, we will discuss how to activate better engines already in the system, or install third-party solutions from Google that significantly improve the quality of information perception. You will learn how to control the parameters of speed and keyness, making the voice of the assistant or navigator more pleasant for hearing.
Basic setting of the speech system synthesizer
The first step to changing voice is to go to the standard operating system settings, where you hide all the voiceovers. On the MIUI shell or the new HyperOS, the path to these settings may vary slightly depending on the Android version, but the logic remains the same. You need to find the section that deals with special features or additional system settings, where the synthesis engine is based.
Once you enter the settings menu, you should look for Special Features, which is often hidden at the bottom of the list or inside the Advanced Settings category. This is where the key subsection of Speech Synthesis (or Text-to-Speech output) is located, allowing you to choose your preferred engine. By default, many Xiaomi devices can activate a simple engine that is inferior in quality to more advanced analogues.
⚠️ Note: When you switch the system engine, some applications that depend on standard Android libraries can temporarily change the way you sound notifications.
In the menu that opens, you'll see a list of available engines. Most often, there's a standard Android TTS and probably already installed Google Speech Services. Choosing your preferred engine is a critical step, because it's the engine that determines the timbre and the tone of your voice. After selecting the engine, be sure to click on the gear icon next to it to open the advanced settings.
Inside the engine settings, you can change the default language, speech speed, and pitch. By experimenting with a pitch slider, you can make your voice lower or higher, adapting it to your personal preferences, and you can also use an example listening feature that allows you to instantly evaluate changes before saving the settings.
💡
Use the “Listen to Example” function after each change in speed or tone to immediately evaluate the result without closing the settings.
Installation and activation of Google Speech Services
The best voice acting to date is provided by Google Speech Services, which is often pre-installed on smartphones but not activated by default. If you don't see Google's options on the list of available engines, you need to download them through the Play Market app store, which provides the most natural sound and support for a large number of languages.
To install, open Play Market and search for “Google Speech Services” or “Google Speech Synthesizer.” Make sure the developer is Google LLC to avoid installing dubious ad counterparts. Once installed, the app will not appear on the menu as a separate icon, as it is a system component that is integrated into Android settings.
☑️ Activation of Google Speech
Once installed, you need to go back to your speech synthesis settings (Settings → Special Options → Speech Synthesis) and select Google Speech Services as your preferred engine. The system can request confirmation to use the data to improve recognition, which is recommended for better performance. Now, when you click on the gear settings, you will see significantly more options than in the standard engine.
An important advantage of Google’s engine is the ability to download high-quality voice packets that take up more disk space but sound much better. From the engine settings menu, select “Voice Installation” or “Voice Data” where you will be offered a list of languages. Click on the desired language (such as Russian) and select the option with the quality icon or the largest file size.
| Parameter | Standard Android TTS | Google Speech Services | Third-party annexes |
|---|---|---|---|
| Sound quality | Basic, robotic | Tall, natural. | Depends on the developer. |
| Traffic consumption | Minimum | Requires packet loading | Often required online |
| Tone adjustment | Limited. | Flexible. | Different. |
| Compatibility | 100% | 99% | Partial |
Setting up voice in Yandex Navigator and Maps
Special attention should be paid to the voice settings in navigation applications, as they often use their own sound packages, ignoring the system settings of the synthesis. In popular applications in Russia, such as Yandex Navigator or Yandex Maps, you can choose the voice of a famous character or celebrity, which makes navigation more enjoyable.
To change your voice in Yandex Navigator, open the app and click on the menu icon (three bars or profile). Go to Settings, then select Sound and Voice. Here you will see a list of available voices, including standard male and female options, as well as special celebrity voices that can be downloaded for free.
If you prefer to use Google Maps, the customization process is also simple. Open the app, click on the profile avatar in the upper right corner and select Settings. In the Navigation Settings section, find Voice during navigation. Here you can select a language and a specific voice if there are multiple options available for the selected locale.
⚠️ Attention: Celebrity voices on navigators can only be accessed if there is an active internet connection for initial download or license verification.
It is worth noting that navigation applications can switch to the system synthesizer if the selected voice packet is damaged or deleted, so if the navigator suddenly "talks" a robot, check for an Internet connection or try reinstalling the voice packet inside the application itself.
Changes to Google Assistant Voice
Google Assistant has its own independent voice settings that are not associated with the speech synthesizer system. You can change not only the timbre (from male to female or vice versa), but also the accent, which allows you to personalize your interaction with the device. This is especially true for users who often use a smart home or control phone voice.
To change your assistant's voice, call it with a long press of the power button or the phrase "OK, Google." Click on your profile icon or avatar in the corner of the screen, then go to Settings. In the list, find the Voice of the Assistant section, where the available options will be presented.
You will be offered several voices, numbered or named by color/name, and you can listen to a short sample of each by clicking on the appropriate button, and once you have selected the appropriate voice, the changes will take effect instantly, and the assistant will respond with a new voice to your next call.
Secret teams for the Assistant
Interestingly, Google periodically updates the Assistant voices, adding new options with improved intonation and emotional coloring, so it is recommended to periodically check this section of settings to see if new, more pleasant voiceovers have appeared.
Third-party applications for speech synthesis
If standard features of Google’s system and services don’t satisfy you, Play Market offers a variety of third-party speech synthesis engines, and one of the most popular and functional solutions is the TTS Server or Speech Services app from various developers, which allows you to use more advanced neural network voices.
Installing a third-party engine requires caution, as some applications may contain intrusive advertising or require excessive permissions. Before installing, read reviews carefully and check the rating of the application. Engines that use cloud technology to generate speech are often a good choice, since they sound the most natural.
Once installed, the activation process is similar to Google Speech: you need to go to the speech synthesis system settings and select the newly installed engine as your preferred one. Some applications may require additional customization within their interface to load voice libraries.
⚠️ Warning: Third-party speech synthesizers may consume more battery power, especially if they use real-time cloud-based audio processing.
Some advanced users use a bunch of third-party apps to create unique voice profiles, but for most tasks, there are enough opportunities provided by the Google ecosystem and standard Android tools.
Frequent problems and ways to solve them
During the setup process, users may encounter a situation where the voice they choose is not applied or sounds intermittent, often due to a lack of RAM or a conflict between several active fusion engines, in which case it is recommended to close all background applications and restart the Xiaomi smartphone.
Another common problem is the lack of sound in certain applications despite correct settings. This can happen if the application uses its own audio engine and ignores the system settings.
If your voice sounds distorted or lost after the system update, try clearing the cache of the Speech Synthesizer app. Go to Settings → Apps → All Apps, search for Speech Synthesizer (or Google Speech Services), click Memory and select Clear Cache. Don't confuse this with clearing the data, as this can reset all your voice packet settings.
💡
Cleaning the cache of a speech system synthesizer often resolves problems with lost or hoarse sound after a MIUI/HyperOS update.
In rare cases, the problem may be that voice packet files are damaged, and if nothing works, delete the voices you have downloaded in your engine settings and download them again, and this is guaranteed to replace the damaged files with working copies.
