What is Spanish Reading Aloud? Recommended Study Methods with Free Text-to-Speech Sites/Apps

Pronunciation and conversation are the hardest aspects to master in any language.
For those who want to become able to speak Spanish, reading text aloud is highly recommended.
First, we will explain the key points for studying Spanish by reading aloud.
Why is Reading Aloud Recommended for Studying Spanish?

When studying Spanish, one study method you should definitely incorporate is reading text aloud.
Spanish is sometimes said to be easy to speak because you just need to pronounce it as it is written in the alphabet.
However, learning correct pronunciation is just as difficult as in other languages.
Even if you understand each individual word, the level of difficulty increases significantly when you try to speak fluently in full sentences.

In such cases, it is recommended to read Spanish aloud while listening to teaching audio to study pronunciation and conversation.
In particular, by incorporating "shadowing," where you read aloud at the same speed as if following the teaching audio, you can remarkably improve your Spanish proficiency.
Why it is Recommended to Use AI Text-to-Speech Sites (Apps) to Create Materials for Spanish Reading Aloud

When studying Spanish by reading aloud, we recommend AI text-to-speech sites (apps) that can turn text into audio using the latest AI.
Until now, to study Spanish by reading aloud, audio included with textbooks or audio from video sites was used.
However, textbook and video site audio often had issues such as:
- The audio is too fast to shadow
- The sound quality becomes too poor when played slowly
- Textbook audio is, conversely, too slow
- There is no audio available for fields of interest
As such, they could be difficult to use for Spanish beginners and intermediate learners.
That is why we recommend utilizing AI text-to-speech sites (apps).
Easy Spanish Reading Aloud with AI Text-to-Speech Sites
AI text-to-speech sites (apps) are services that can automatically read out the text you input.
Just by inputting Spanish text, anyone can easily create materials for reading aloud.
The biggest point is that you can change the reading speed to create audio for reading aloud slowly.
Since the sound quality does not degrade even if you lower the speed, it is ideal for starting reading aloud from a slow pace.
You can easily create not only standard materials like daily or travel conversation but also audio materials using technical terms useful for business.
Some AI text-to-speech sites (apps) like Ondoku are available for free, so we recommend starting by experiencing reading aloud and shadowing with AI-generated audio!
Reading Aloud is Also Recommended for Improving Listening Skills

Reading Spanish aloud is recommended not only for speaking skills like pronunciation and conversation but also for improving listening skills.
There is an important point common to studying any foreign language.
That is: what you can speak, you can hear.
Words you can say, you can hear; and sentences you can say, you can also hear.
By using AI text-to-speech sites (apps) like Ondoku to read Spanish aloud and shadow, you can increase your repertoire of sentences you can speak.
The more you increase your speaking repertoire, the more your repertoire of sentences you can understand by listening will grow.
By training your pronunciation and conversation, you can also boost your listening skills.
Shadowing is Recommended for Studying Spanish via Reading Aloud
So, what is the best method if you are going to study Spanish by reading aloud?
"Shadowing" is the recommendation!
With "shadowing," a standard language study method, you can effectively acquire Spanish pronunciation and conversation skills.
What is Shadowing? Key Points of the Recommended Study Method

Shadowing is a very effective, standard study method when studying foreign languages by reading aloud.
The method for shadowing is very simple.
- Play the Spanish teaching audio
- Read aloud following the teaching audio
That's it.
However, there are points where it differs from normal reading aloud.
Read aloud as if following the teaching audio
In normal reading aloud, you often finish listening to a sentence before reading it aloud, right?
In shadowing, that is not the case; as soon as the teaching audio starts playing, you start reading aloud immediately as if following it.
Specifically, it is recommended to read aloud about 1 to 2 words behind the teaching audio.
Read exactly what you hear with your ears
In shadowing, you read aloud the content you hear from your ears exactly as it is.
In normal reading aloud, you read while looking at the text with your eyes, right?
In shadowing, you read aloud by following only the audio heard from your ears.
If Shadowing is Difficult, Play the Teaching Audio Slowly

However, when you have just started studying Spanish, even if you try to shadow, the audio might be too fast and your reading can't keep up.
In such cases, play the audio slowly.
There is no shame in starting shadowing at a slow speed.
In fact, reading aloud slowly is necessary for studying pronunciation and conversation.
Once you become able to read aloud well at a slow speed, it is recommended to gradually increase the speed.
AI Text-to-Speech Apps (Sites) are Recommended for Reading Aloud Slowly
When shadowing at a slow speed, utilizing AI text-to-speech apps (sites) is the best!
When you want to read aloud slowly, if you lower the playback speed on an audio player app, the sound quality often degrades.
In pronunciation and conversation study, there are many cases where you might lower the playback speed to about half.
However, if you lower the playback speed of normal audio that much, fine pronunciations and intonations become hard to understand.
With AI text-to-speech apps (sites), you can easily set the speed at which the text is read.
By setting it to a slow speed such as 0.5x or 0.3x, you can create teaching audio that is slow yet easy to hear, perfect for shadowing.
Shadowing is also explained in this article. Please take a look.
