    What Are The Top Ten Speech Recognition APIs

    What Are The Top Ten Speech Recognition APIs

    What are Speech Recognition APIs?

    Speech Recognition APIs are a set of computer programs. It aims to record, interpret, and convert human speech input to text. The API breaks the audio to take out results. It breaks a voice recording into individual tones and then analyzes each tone. It does this by using algorithms to find the word that is most likely to match that language. The API then converts those tones to text.

    Speech Recognition API uses Natural Language Processing (NLP) and deep neural learning networks. NLP is also a method by which computers analyze and understand the meaning of human language. Doing so, it can interpret and convert into a digital format and analyze the content.

    Now the API can make decisions based on programming and language patterns. It makes assumptions about what the user is actually saying. After determining the conversation, it transcribes the conversation into text.

    It sounds simple but in reality, it is quite difficult. The advances in technology make these diverse and complicated processes lightning fast.

    Top 10 Speech Recognition APIs

The API can also suppress noise from a variety of sources. Also, SpeechAPI enables access to speech segments in an audio file. Moreover, it allows users to classify them according to various characteristics like mood, the language of the speaker, age, and gender.
    • The API supports a limited number of languages.
    • The API is offered free of charge.
    • It has simple and easy-to-understand documentation. It can be used to embed the API with little programming effort.
    Speech-to-Text API

    The Speech-to-Text API is a basic API. It allows the user to convert audio input into written text.

    API Features:

    • Machine-learning technology is applied in the API. This helps the users to transcribe audio input with accuracy. It can also convert both short and long audio files.
    • Speech-to-Text API only supports the English language. Also, it can detect accents for easier conversion with minimal deviation.
    • The API is easy to use. It has simple documentation that enables users to get started implementing it.
    TexttoSpeech API

    The Voice RSS API TexttoSpeech is a basic API. It basically converts text input into speech.

    API Features:

    • There is a speech synthesis system provided by the API. It helps to convert the text in normal speech into human speech. With a few lines of code, you can connect to the API and allow your application to serve audio.
    • TexttoSpeech API offers a wide range of human voices. It also supports 26 languages.
    • Complete documentation is also provided in various programming languages. This also helps to integrate the API on any platform.
    Rev. AI API
