What is reading aloud in Spanish? Recommended study methods using free text-to-speech sites and apps

Pronunciation and conversation are difficult to master in any language.
If you want to be able to speak Spanish, we recommend reading sentences out loud.
First, we will explain the key points for studying Spanish by reading aloud.
Why is reading aloud a good way to learn Spanish?
A great way to study Spanish is to read sentences aloud .
Spanish is sometimes said to be easy to speak because all you have to do is pronounce the words the way they are written in the alphabet.
But, just like any other language, learning the correct pronunciation is difficult.
Even if you understand each individual word, the difficulty level increases dramatically when you try to speak them fluently as sentences.

In such cases, we recommend studying pronunciation and conversation by reading Spanish aloud while listening to the audio teaching materials .
In particular, by incorporating "shadowing," which involves reading aloud at the same speed as the audio in the teaching materials, you can rapidly improve your Spanish skills.
Reasons why it is recommended to create teaching materials using AI text-to-speech sites (apps) for Spanish reading aloud
When studying Spanish by reading aloud, we recommend an AI reading site (app) that uses the latest AI to convert text into audio.
Until now, to study Spanish by reading aloud, students used the audio included in textbooks or audio from video websites.
But the audio in textbooks and video sites
- The audio is too fast to shadow
- Playing it slowly makes the sound quality worse
- On the other hand, the audio in textbooks is too slow
- There is no audio in the field I'm interested in
As a result, it can be difficult to use for beginners and intermediate learners of Spanish .
What I recommend is to make use of an AI text-to-speech website (app).
Easy Spanish reading with AI reading site
An AI reading site (app) is a service that can automatically read out text you enter .
By simply inputting Spanish text , anyone can easily create reading materials .
The biggest feature is that you can change the reading speed to create audio that reads slowly aloud.
The sound quality does not deteriorate even if you slow down the speed , so it is perfect for starting to read aloud at a slower speed.
In addition to standard teaching materials such as everyday conversation and travel conversation, you can easily create audio teaching materials using specialized terms useful in business.
There are some free AI reading sites (apps) like "Ondoku," so we recommend that you first try out reading aloud and shadowing with an AI reading voice!
Reading aloud is also recommended for improving listening skills.
Reading aloud in Spanish is recommended not only for improving speaking skills such as pronunciation and conversation, but also for improving listening skills .
There are some important points that apply to studying any foreign language.
That means you can hear what you can say .
I can hear the words that are spoken and I can also understand the sentences that are spoken.
By using an AI text-to-speech site (app) such as "Ondoku" to read aloud and shadow Spanish, you can increase the repertoire of sentences you can speak.
The more you increase your speaking repertoire, the more you will be able to understand sentences.
By practicing your pronunciation and conversation skills, you can also improve your listening skills.
Shadowing is recommended if you want to study Spanish by reading aloud
So, what's the best way to learn Spanish by reading aloud?
I recommend "shadowing"!
The classic language learning method, "shadowing," is an effective way to improve your Spanish pronunciation and conversation skills.
What is shadowing? Recommended study methods
Shadowing is a classic and highly effective study method for studying a foreign language by reading aloud.
The shadowing method is very simple.
- Play audio for Spanish language learning materials
- Read aloud following the audio of the material
That's it.
However, there are some differences from normal reading aloud .
Read aloud while following the audio of the teaching materials.
When reading aloud normally, you usually listen to a sentence and then read it aloud.
In shadowing, however, as soon as the audio material starts playing, you begin reading aloud, following along.
Specifically, it is recommended that you read aloud one or two words behind the audio in the teaching materials.
Read aloud what you hear
In shadowing, you read aloud exactly what you hear.
In normal reading aloud, you read the text aloud while reading it with your eyes.
In shadowing, you read aloud by following only the audio you hear .
If shadowing is difficult, play the audio material slowly.
However, when you first start learning Spanish, you will often find that when you try to shadow, the audio is too fast and you cannot keep up with the reading .
In that case, try playing the audio slower .
There's no shame in starting out shadowing at a slower speed.
In fact, reading aloud slowly is necessary for studying pronunciation and conversation .
Once you've become comfortable reading aloud at a slow speed, it's recommended that you gradually increase your speed.
If you want to read aloud slowly, we recommend an AI reading app (site)
When shadowing at a slow speed, it's best to use an AI reading app (site)!
When you want to read aloud slowly, lowering the playback speed on the audio player app results in poor sound quality.
When studying pronunciation or conversation, the playback speed is often slowed down to about half speed .
However, if you slow down the playback speed of normal audio to that extent, it becomes difficult to hear subtle pronunciation and intonation.
With an AI reading app (site), you can easily set the speed at which text is read aloud.
By setting the speed to a slower speed, such as 0.5x or 0.3x, you can create audio material that is slow but easy to listen to, perfect for shadowing.
