No. You need to be intelligible, not native-sounding, and those are two different targets. One takes a few weeks of focused work. The other takes years and buys you almost nothing you actually want.
Nearly every learner who worries about their accent is worrying about the wrong half of the problem. The things that genuinely make you hard to understand are small, specific, and fixable. The thing people obsess over, sounding like a local, is neither the cause of the problem nor the cure.
What actually makes you hard to understand
When someone squints and says "sorry, again?", it is usually one of three things, and an accent is rarely the one.
A sound that changes the word. Every language has a short list of sounds that carry meaning, where swapping one for its neighbor turns a word into a different word. Miss one of those and the listener does not hear you with an accent. They hear a different word, or no word at all.
Stress in the wrong place. Put the emphasis on the wrong syllable and a familiar word can stop being recognizable. This trips people up more than any individual sound, because the listener is matching the shape of the word before they get to its parts.
Hesitation. This is the big one, and nobody counts it as pronunciation. A phrase delivered in one piece is easy to follow. The same phrase delivered as a word, a pause, another word, a correction, and then the rest is hard work for the listener, no matter how clean each sound was. Broken rhythm costs you more comprehension than a strong accent ever will.
The pronunciation that does matter
Some of it is worth real effort. Not because it sounds nicer, but because meaning rides on it.
Sounds that distinguish words in that specific language. In Spanish the five vowels are pure and stable, and sliding them the way English does is what makes learners hard to follow. In English, learners whose first language does not separate certain consonants will merge word pairs that native speakers keep apart. Find the handful of contrasts your language pair actually collides on. It is a short list, and it is the highest-value pronunciation work you will ever do.
Tones and pitch, where the language uses them. In Mandarin, tone is not accent. It is part of the word, the same way a letter is. Getting it wrong is closer to a spelling mistake than a foreign accent. Japanese pitch and mora timing work similarly: rhythm is carrying information, not decoration.
Word and sentence stress. Learn where the stress falls when you learn the phrase, not afterwards. It comes free if you learn the phrase as a whole and say it out loud, and it is painful to retrofit later.
That is the entire list. Everything on it exists because a listener needs it to decode what you said.
The pronunciation that does not matter
The perfect rolled R. The exact vowel color a native from that particular city uses. The last five percent that separates "clearly foreign but easy to follow" from "could pass as local."
Native speakers understand accented speech constantly. Their own language is full of regional accents they parse without effort, and most of them talk to non-native speakers regularly. Your accent is not the obstacle you imagine. In many places it is the reason people are patient with you, because it tells them immediately that you are learning.
An accent is also not a defect to be removed. It is information about where you came from. Plenty of people who speak a second language at a very high level keep a clear accent for life, and it costs them nothing.
Why chasing a native accent backfires
Here is the trap. You decide your accent is not good enough, so you start monitoring every sound as it leaves your mouth. Monitoring is slow. You hesitate, restart, second-guess a word mid-phrase.
Now you are harder to understand than you were before, and for exactly the reason from the first section. You traded a slight accent, which listeners handle easily, for broken rhythm, which they do not.
The self-consciousness is worse than the accent. A learner who says a clumsy sentence at a normal pace and keeps going gets understood. A learner with better sounds who stops three times in one sentence does not. Confidence is not a personality trait here. It is a comprehensibility feature.
What to practice instead
Say whole phrases out loud, not words. Rhythm lives at the phrase level, so a phrase drilled as one unit comes out with its stress and timing already correct. Assembling it word by word is how the timing gets destroyed.
Record yourself and listen back. Two minutes of anything, played back. You will hear where you stall and which words you avoid. You will hear your rhythm far more accurately than you can while you are busy producing it.
Ask for correction on meaning only. When someone corrects you, the useful question is not "did that sound native?" It is "did that sound like a different word?" Fix the ones that change meaning. Let the rest go.
Shadowing helps here specifically. Play audio and speak along a beat behind it. Since the words are handed to you, it does nothing for recall, but it is genuinely good for mouth mechanics and rhythm. This is the one job shadowing does better than anything else.
Then stop working on it. Accent work has a point of diminishing returns and it arrives early. Once you are being understood, more pronunciation drilling is not what is standing between you and a conversation.
An honest note
There are situations where accent goes beyond intelligibility. Acting, voice work, and a few jobs where sounding local is the actual product. If that is you, this post is not your answer, and you want a pronunciation coach rather than a learning app.
For everyone else, the goal is being understood the first time, at normal speed, without the listener working for it. That comes from a short list of meaning-carrying sounds, correct stress, and phrases that arrive in one piece. No app can remove an accent, and one that promises to is selling you the wrong goal. What you can build is the ability to say the thing, cleanly, at speed, without stopping in the middle.
FAQ
Do you need a perfect accent to speak a foreign language? No. The goal is intelligibility, not sounding native. Listeners understand accented speech easily and do it all the time. What actually causes misunderstandings is a small set of sounds that change word meaning in that language, stress on the wrong syllable, and hesitation that breaks a phrase into pieces. Fix those and a noticeable accent costs you nothing.
Can native speakers understand you if you have a strong accent? Usually yes, as long as you are hitting the sounds that carry meaning and keeping a steady rhythm. Native speakers already handle a wide range of regional accents in their own language. A strong accent delivered fluently is easier to follow than a mild accent delivered with constant pauses and restarts.
Which parts of pronunciation should I actually work on? The sounds that distinguish one word from another in the language you are learning, tones or pitch where the language uses them, and word stress. These carry meaning, so getting them wrong produces a different word rather than a foreign-sounding one. Everything past that is polish and can wait indefinitely.
How do I improve my accent on my own? Say whole phrases out loud rather than individual words, so stress and rhythm come along with them. Record yourself and listen back, which is the most honest feedback available without another person. Use shadowing, speaking along a beat behind real audio, to train mouth mechanics and timing. Focus corrections on sounds that change meaning and ignore the rest.
