I hope that this post helps you enjoy your multimedia experience. Additionally, I showcased how you can use SSML language to improve the quality of the speech. It allows you to convert any length text into an MP3 file.

In this post, I showed you how to use the AWS Polly service to convert text to audio by employing a simple Python script. Now you can upload your newly generated MP3 file on Amazon Music and play it on Alexa! The output of the script allows you track the execution, but you can comment it out. Type python polly.py in the console to convert your story file into an audio file. Open a text editor (Nano or Vim on Linux/Unix/MacOS or Notepad on Windows), type your story and save the file under “story.txt” name.Ĥ. The output MP3 file should work on most new audio players.ģ. The trick is that the cat command simply appends each file to another and won’t recreate metadata for the final MP3 file. To have only one MP3 file, I simply merged the files using the cat command (cat polly_out0.mp3 polly_out1.mp3>result.mp3). The script will generate many MP3 files because each new line initiates an MP3 file generation. Print 'Removing temporary files: ' + execute_command Subprocess.call(execute_command, shell=True) For example, for a pause between sentences you can use markup where 1s stands for one second pause.į = codecs.open("story.txt", encoding='utf-8')Ĭommand = 'aws polly synthesize-speech -text-type ssml -output-format "mp3" -voice-id "Salli" -text ".mp3'.format(u''.join(str(cnt)).encode('utf-8'))Ĭommand = command.format(rendered.encode('utf-8'), file_name)Įxecute_command = 'cat ' + file_names + '>result.mp3' SSML is a markup language with various tags. Therefore, I used Speech Synthesis Markup Language (SSML) rather than simple text. However, I found that the MP3 output file lacks pauses between the sentences and paragraphs. txt file and pass it to AWS CLI command for the conversion. The script relies on the AWS CLI tool and a standard Linux/Unix command: ‘ cat’. Therefore I decided to create a simple Python script that would allow me to input an unlimited size text file and would output an mp3 file.
I was looking for a quick way to test the service locally from my computer with minimal configuration.
The second solution requires the installation of Node.js. The first solution is a full-scale production system that requires good understanding of AWS services and the configuration of the services. Wouldn’t it be ideal if an AWS CLI command would allow you to input an unlimited size text file that would be automatically converted to an MP3 file?Ī quick search reveals two solutions: a cloud solution based on AWS Lambda and AWS Batch, and a Node.js based solution. If you want to convert long form text, such as a book, to speech using Amazon Polly, you need to break up your text into chunks of 1500 characters. To try the Amazon Polly service, in the Plain text tab, paste your text and listen the output. You can also use the AWS Command Line Interface (AWS CLI) to perform the conversion from your AWS Management Console.Ĭopy a small amount of text that you want to try, and then open the console.Ģ.

Then you can listen to the converted text or download it as an MP3 file. With Amazon Polly, you can convert your RSS feed or email, and store the synthesized speech in the form of audio files.Ĭurrently, the Amazon Polly console allows you to paste text that is up to 1500 characters long, choose your language and region, and choose a voice.

Text-to-speech technology can turn any digital text into a multimedia experience, so people can listen to news, blog articles, or even a PDF document, while multitasking or on-the-go.
