Audio De Texto A Voz
Chrystal Dueno
Fine-tune synthesized speech audio to fit your scenario. Define lexicons and control speech parameters such as pronunciation, pitch, rate, pauses, and intonation with Speech Synthesis Markup Language (SSML) or with the audio content creation tool.
Differentiate your brand with a unique custom voice. Develop a highly realistic voice for more natural conversational interfaces using the Custom Neural Voice capability, starting with 30 minutes of audio.
Drag and drop an audio or video file into a new Descript project to upload it. A transcript will automatically generate and sync to your audio, including dialogue and even "wordless media" like sounds, and pauses. If there are multiple speakers in your audio, Descript will automatically identify and label them for you.
By default, your new transcript will be synced to your editing timeline. You can delete or rearrange the text to edit your audio, letting you do stuff like remove filler words in one click. If you want to fix any transcription errors, like a misspelled name, highlight the text and enter Correct mode by pressing 'C' to fix your transcript without affecting the audio.
Once your transcript is polished, head over to Publish > Export and choose an export option. You can export your transcript as plain text, rich text, markdown, HTML, Word doc, or even an SRT or VTT subtitle file. You can also publish it as a web link to share or embed your transcript alongside the audio with Descript's media player.
Descript does more than just transcribe audio. It can also generate audio based on your text to expand your creative options. Keep your words and change your voice, or cloning your voice to add to your original audio without rerecording.
Whether you're a YouTuber, podcaster, or just want to transcribe an audio file, Descript's 95% accurate AI transcription gets you most of the way. From there, you can remove filler words in one click, automatically flag likely transcription errors, and make bulk corrections across your entire transcript.
Export your transcribed audio in your choice of format, including or excluding speaker labels, time codes, and markers. Plus, AI Actions make it easy to turn your transcript into blog posts, social media posts, or even a script based on your prompts.
Far from it. Descript is an all-in-one audio and video editor. With features like automated filler word removal, voice cloning, and Studio Sound voice enhancement, Descript uses AI to streamline your entire production workflow.
An audio transcriber is someone or software that converts audio into written text. Riverside.fm is an excellent example of an online audio transcriber. Its online transcription services give you instant and accurate results, converting your audio into text in minutes.
You can create audio transcription manually or through dedicated software. Manually, you can either listen and transcribe audio yourself or hire someone. This may be expensive, however. A lot of people save time and money by using audio transcription software. Although, these are not always accurate and rely on high-quality audio for good results. Riverside.fm records in high-resolution WAV files to make sure audio transcriptions are reliable and accurate. For more on how to attain high-quality audio, check out our list of the best voice recorder apps.
The Speech service allows you to convert text into synthesized speech and get a list of supported voices for a region by using a REST API. In this article, you learn about authorization options, query options, how to structure a request, and how to interpret a response.
Use cases for the text to speech REST API are limited. Use it only in cases where you can't use the Speech SDK. For example, with the Speech SDK you can subscribe to events for more insights about the text to speech processing and results.
The text to speech REST API supports neural text to speech voices in many locales. Each available endpoint is associated with a region. A Speech resource key for the endpoint or region that you plan to use is required. Here are links to more information:
You can use the tts.speech.microsoft.com/cognitiveservices/voices/list endpoint to get a full list of voices for a specific region or endpoint. Prefix the voices list endpoint with a region to get a list of voices for that region. For example, to get a list of voices for the westus region, use the endpoint. For a list of all supported regions, see the regions documentation.
You should receive a response with a JSON body that includes all supported locales, voices, gender, styles, and other details. The WordsPerMinute property for each voice can be used to estimate the length of the output speech. This JSON example shows partial results to illustrate the structure of a response:
If you've created a custom neural voice font, use the endpoint that you've created. You can also use the following endpoints. Replace deploymentId with the deployment ID for your neural voice model.
The preceding regions are available for neural voice model hosting and real-time synthesis. Custom neural voice training is only available in some regions. But users can easily copy a neural voice model from these regions to other regions in the preceding list.
If you're using a custom neural voice, the body of a request can be sent as plain text (ASCII or UTF-8). Otherwise, the body of each POST request is sent as SSML. SSML allows you to choose the voice and language of the synthesized speech that the text to speech feature returns. For a complete list of supported voices, see Language and voice support for the Speech service.
This HTTP request uses SSML to specify the voice and language. If the body length is long, and the resulting audio exceeds 10 minutes, it's truncated to 10 minutes. In other words, the audio length can't exceed 10 minutes.
The supported streaming and nonstreaming audio formats are sent in each request as the X-Microsoft-OutputFormat header. Each format incorporates a bit rate and encoding type. The Speech service supports 48-kHz, 24-kHz, 16-kHz, and 8-kHz audio outputs. Each prebuilt neural voice model is available at 24kHz and high-fidelity 48kHz.
If you select 48kHz output format, the high-fidelity voice model with 48kHz will be invoked accordingly. The sample rates other than 24kHz and 48kHz can be obtained through upsampling or downsampling when synthesizing, for example, 44.1kHz is downsampled from 48kHz.
When you're using the Authorization: Bearer header, you need to make a request to the issueToken endpoint. In this request, you exchange your resource key for an access token that's valid for 10 minutes.
This example is a simple HTTP request to get a token. Replace YOUR_SUBSCRIPTION_KEY with your resource key for the Speech service. If your subscription isn't in the West US region, replace the Host header with your region's host name.
This example is a simple PowerShell script to get an access token. Replace YOUR_SUBSCRIPTION_KEY with your resource key for the Speech service. Make sure to use the correct endpoint for the region that matches your subscription. This example is currently set to West US.
cURL is a command-line tool available in Linux (and in the Windows Subsystem for Linux). This cURL command illustrates how to get an access token. Replace YOUR_SUBSCRIPTION_KEY with your resource key for the Speech service. Make sure to use the correct endpoint for the region that matches your subscription. This example is currently set to West US.
This C# class illustrates how to get an access token. Pass your resource key for the Speech service when you instantiate the class. If your subscription isn't in the West US region, change the value of FetchTokenUri to match the region for your subscription.
The access token should be sent to the service as the Authorization: Bearer header. Each access token is valid for 10 minutes. You can get a new token at any time, but to minimize network traffic and latency, we recommend using the same token for nine minutes.
To use Microsoft Entra authentication with the Speech to text REST API for short audio, you need to create an access token.The steps to obtain the access token consisting of Resource ID and Microsoft Entra access token are the same as when using the Speech SDK.Follow the steps here Use Microsoft Entra authentication
