Text to speech: how to voice text and get WAV
"Text to speech" is a web tool that reads your text aloud with a browser voice available, or creates a synthetic recording using eSpeak NG. It supports 38 languages and allows you to get a WAV audio file or SRT subtitles. The tool does not require registration and does not automatically save history. In this article we will walk through how to use it step by step, what to pay attention to when checking the result, and what limitations are important to consider. All examples in the article are fictional illustrations, not results of real tests.
Open tool: Text to speech ↗What the tool can do and what it is suitable for
"Text to speech" accepts text up to 3000 characters for voice output. You select the output language, press 'Generate' and get the result in a separate panel. If the browser supports speech synthesis, the text is read by the device voice. If not, eSpeak NG is used - a synthetic voice that supports 38 languages. This is not a recording of a live announcer, but machine pronunciation, so the intonation may be flat and not always natural.
The tool is suitable for everyday tasks: listen to a draft article, check how a phrase sounds in a foreign language, create an audio version of a short instruction. It is not intended for professional voiceover, podcasts or video dubbing. It also does not clone a voice and does not create audio/video. If you need a realistic voice, this is not the tool.
Volume limits: the first field - up to 8000 characters, but for voice output - up to 3000 characters. This is approximately 400-500 words. If the text is longer, split it into parts and voice them sequentially. Remember that queue and availability may change, and the model may make mistakes.
Example: insert the text 'Welcome to Iskra AI. Turn a small idea into something useful.' Select English language and press 'Generate'.
Step-by-step scenario: from text to audio
Step 1. Prepare text. Make sure it does not exceed 3000 characters. Remove unnecessary characters if they are not needed for pronunciation. Step 2. Enter text in the field 'Your text or idea'. Step 3. Select output language. Available languages depend on the device and eSpeak NG. Step 4. Press 'Generate'. The result appears in a separate panel.
Step 5. Listen to the audio. If the voice sounds wrong, check if the browser supports the selected language. Sometimes changing the browser or selecting another language helps. Step 6. Copy or download the result in WAV format. You can also get SRT subtitles if needed. Step 7. If the text is long, repeat the steps for each part.
Important: the tool does not save history automatically. If the result is needed later, download it immediately. Do not upload documents and do not use integrations - they are not available. Everything is done manually in the web form.
Example: text 'Connection check. Today is 25 degrees warmth.' select Russian language, press 'Generate', listen and download WAV.
How to check the result
Listen to the audio completely. Pay attention to the pronunciation of names, numbers, abbreviations. eSpeak NG may read them differently than you expect. If something sounds wrong, try reformulating the text: replace digits with words, expand abbreviations. This is especially useful for foreign words.
Compare the audio duration with the expected. If the text is long and the audio is short, perhaps part of the text was not voiced. Check if the character limit has been exceeded. Also make sure the correct language is selected: if the language does not match the text, pronunciation will be strange.
If you use SRT subtitles, open them in a text editor and check the timings. They may shift. Remember that the tool is not intended for precise synchronization. For educational purposes it is better to listen and verify with the original text.
Example: if the number '2024' is read as 'two thousand twenty four', and you need 'twenty twenty four', write it as words.
Limitations and typical errors
The tool does not support export to DOCX or PDF, there is no batch processing, automatic saving, integrations, OCR, settings panels, version comparison, direct publishing, email delivery, document upload, premium plan, registration, voice cloning, photorealistic image generation or audio/video generation. Everything beyond reading text aloud is unavailable.
Browser voices may be unavailable on some devices. In this case eSpeak NG is used, which sounds more robotic. Do not expect natural intonation. Also there is no speed, timbre or pause adjustment. If you need to change the tempo, you have to split the text into parts or use other means.
Limits: text for voice output - up to 3000 characters, first field - up to 8000, second - up to 1000. Audio in browser - up to 20 MB or 5 minutes. Images - up to 4 MB. The model may make mistakes, and the queue may be busy. Do not use the tool for critical tasks where error is unacceptable.
Example: if you inserted 3500 characters, only the first 3000 will be voiced. Split the text into two parts.
Practical example: voicing an instruction
Suppose you need to voice a short instruction for using a coffee machine. Text: 'Pour water into the reservoir. Insert the filter. Add ground coffee. Press start. Wait two minutes.' This is 150 characters. Select Russian language, press 'Generate'. Listen. If the voice pronounces 'start' as 'start', everything is fine.
If you need to voice in English, translate the text and select English. Remember that eSpeak NG may pronounce words with an accent. Check each word. If something is wrong, change the spelling: for example, 'coffee' may sound like 'coffee' in Russian, but in English it will be correct.
This scenario is a fictional example. In reality you can use the tool for any texts, but always check the result. Do not rely on automation in important matters.
Example: text 'Pour water. Insert filter. Add coffee. Press start.' select Russian, generate and download WAV.
Tips for effective use
Break long texts into meaning blocks of 200-300 characters. It is easier to check pronunciation and fix errors. Use punctuation: periods and commas help the synthesizer make pauses. But do not overuse: eSpeak NG may ignore some signs.
If you need to voice numbers, write them as words. For example, replace '25' with 'twenty five'. This improves intelligibility. For abbreviations add spaces or expansion: 'MCHS' may sound as 'em che es', as 'M C S' - as individual letters.
Check available voices in your browser. In Chrome and Edge voices may differ. If you do not like the voice, try another browser. But remember: the tool does not guarantee the presence of a specific voice. Everything depends on the device.
Example: instead of '25°C' write 'twenty five degrees Celsius'.
The 'Text to speech' tool is a simple way to voice text without complex settings. It is suitable for quick tasks: listen to a note, check pronunciation, create an audio file. But it has limitations: character limit, dependence on the browser, lack of fine tuning. Always check the result and do not use the tool for critical tasks. Remember, this is not a replacement for professional voiceover.
