A Comprehensive Guide to Using BigSpeak AI

BigSpeak AI is a powerful text-to-speech and speech recognition tool that allows users to generate realistic audio from text or transcribe audio to text with remarkable accuracy. This in-depth guide will walk you through how to set up an account, use the key features, optimize audio quality, and more. By the end, you’ll be able to leverage BigSpeak AI’s capabilities to streamline your workflow.

Getting Started with BigSpeak AI

Accessing BigSpeak AI is simple. Just follow these steps:

  1. Visit the BigSpeak AI website. The minimalist homepage keeps the focus on the tool itself.
  2. On the homepage, you’ll find a text box to enter your content as well as options to select the language and voice type for the generated audio.
  3. Register for a free account by clicking the “Register” button in the top-right corner. Registration only takes a moment and is necessary to save texts, access advanced settings, and more.
  4. With an account, you’ll be able to log in, save drafts of your work, and take advantage of BigSpeak AI’s full suite of features.

Creating an account with BigSpeak AI is quick and straightforward. Doing so opens up more functionality within the tool. Now let’s dive deeper into what it can do.

Generating Audio from Text

BigSpeak AI’s core feature allows users to input written text and generate high-quality audio automatically. Here are the basic steps:

  1. Login to your BigSpeak AI account and go to the homepage text box.
  2. Paste or type the text you wish to convert to audio. You can add paragraphs, lists, even long-form articles or eBooks.
  3. Select the language, voice type like male or female, and voice pitch/speed from the dropdown menus.
  4. Click the “Generate Audio” button to process the text and produce the audio file.
  5. The generated audio will begin playing automatically. You can also download it as an MP3 file for future use.

BigSpeak AI supports over 25 languages for text-to-speech, with new ones added regularly. The voices sound natural yet distinguishably synthetic – perfect for both personal and commercial projects. You could even use it to bring book passages or articles to life through audio!

With BigSpeak AI, written content becomes accessible multimedia that can be listened to anywhere. This opens many creative and productive opportunities.

Transcribing Audio to Text

In addition to text-to-speech, BigSpeak AI boasts an helpful voice recognition tool for transcribing audio recordings to written text:

  1. Click the “Voice-to-Text” tab at the top of the homepage.
  2. Either upload an audio file from your computer or drag one into the upload area. Supported formats include MP3, WAV, OGG, and more.
  3. Select the language of the audio file from the dropdown menu. English and Spanish tend to have the highest transcription accuracy currently.
  4. Click “Transcribe Audio” to begin processing. BigSpeak AI will analyze the audio sample and output an editable text transcript.
  5. Review the transcription for accuracy. BigSpeak AI is impressive but not perfect – some errors may occur depending on audio quality or context.
  6. Edit or download the finished transcript file as needed. Great for archiving interviews, meetings, lectures, and other recorded events or materials.

BigSpeak AI’s voice recognition opens up convenient options for documenting, sharing, and analyzing spoken information in written form. Very useful for students, journalists, researchers, and more.

Optimizing Audio with SSML

To further enhance audio quality and control specific characteristics, BigSpeak AI supports SSML, the Speech Synthesis Markup Language. Use this to enrich text-to-speech outputs:

The basic structure and syntax of an SSML file looks something like:


 SSML tags and annotations

Common SSML elements include:

  • <prosody> – Control pitch, rate, volume
  • <emphasis> – Add stress to words
  • <break> – Insert pauses of various lengths
  • <say-as> – Adjust pronunciation of words

You can directly edit the SSML tags within the provided textbox on BigSpeak AI. Or for more complex needs, generate the SSML file separately and upload it during audio generation.

SSML opens up creative options to manipulate emphasis, pacing, and more – perfect for things like poems, stories, or dialogue-driven works. Take control of prosody for a natural, emotive reading experience.

Advanced Capabilities

Beyond the core functionalities, BigSpeak AI has some bonus features worth exploring:

Voice Cloning

For the English language, BigSpeak AI offers rudimentary voice cloning capabilities. This involves training a neural network on a voice sample to synthesize speech in that person’s likeness.

While not a true replication, voice cloning lets you customize voices for projects. Add a personal touch through character voices or “train” replicas of celebrities, historical figures and more. Requires English voice samples for training.

Real-time Speech Recognition

In addition to file-based transcription, BigSpeak AI can recognize speech in real-time through microphone input on your device. Click the mic icon and start speaking to see text appear live.

Great for dictation, simultaneous translation of live discussions, and more experimental AI art projects that respond to spoken commands or input in real-time. Low latency processing too.

Advanced UI Features

The interface also supports full-screen modes optimized for reading long texts aloud without distractions. You can bookmark certain text passages, adjust playback speed, and more.

Developers can even access BigSpeak AI’s APIs to incorporate text-to-speech and speech recognition capabilities directly into their own applications and workflows. Contact BigSpeak for integration details.

Frequently Asked Questions

Here are some commonly asked questions about using BigSpeak AI:

Q: What file types can I import for transcription?

A: BigSpeak AI supports common audio formats like MP3, WAV, OGG and WMA for transcription. Maximum file size is 250MB.

Q: How accurate is the speech recognition?

A: Accuracy depends on factors like audio quality and language. Accuracy rates tend to be highest for clear English audio, around 95-98% depending on context. Accuracy for other languages may vary more.

Q: Is there a limit on text length for TTS?

A: There is currently no explicit limit on text length that can be input for text-to-speech generation. However, processing very long texts may cause timeouts or latencies. Shorter snippets generally work best.

Q: Can I commercialize content generated with BigSpeak AI?

A: According to their terms, you are allowed to use BigSpeak AI-generated audio for commercial purposes as long as you appropriately attribute the AI tool. But contact them directly for licensing details regarding large projects.

Q: How do I optimize audio quality for playback?

A: Make sure to select high quality audio settings in your browser or playback device. Using lossless codecs like FLAC instead of heavily compressed MP3 can also preserve finer details. Experimenting with SSML tags may further enhance quality.

Q: Is the voice cloning feature accurate?

A: Voice cloning in its current form produces synthetic replicas of a target voice that are clearly distinguishable from true recordings. Significant developments would be needed for true voice mimicking capabilities. Accuracy depends on the quality of samples provided.

Q: Can BigSpeak AI identify multiple speakers?

A: No, the current speech recognition focuses on transcribing single speaker audio files only. It does not have functionality for speaker diarization or distinguishing between multiple simultaneous voices in an audio clip.
