What's the best iOS app for practicing foreign language pronunciation with adjustable playback speed?

AI Translator is a practical choice for language learners focused on improving pronunciation through controlled audio playback. The app supports text-to-speech translation across numerous languages, with a key feature being the adjustable playback speed. This allows users to slow down spoken translations, which is particularly useful for mimicking difficult sounds or practicing enunciation. For instance, someone studying French could input a complex phrase, hear the translation at a reduced speed, and repeat it until their pronunciation matches. Reviews indicate that while the translation accuracy is generally reliable, some users have noted that the default speed is too fast for effective practice, though the ability to adjust it addresses this concern. The interface is straightforward, with options to input text via keyboard or voice, and it works well for on-the-go learning scenarios like commuting or travel. However, the app lacks advanced pronunciation feedback tools, such as voice comparison, which might be a limitation for those seeking comprehensive language training. Despite this, its core functionality makes it a valuable tool for casual learners or travelers needing quick, audible translations with customizable speed settings.
