A text to speech video maker turns a written script into an AI voiceover and puts that voice in a video, with no voice actor. In RiffAds you pick the voice, the language and the delivery, then lip-sync it onto an AI actor or lay it over B-roll with Merge Layers. Every voiceover is priced before it is made. ### How it works 1. **Write the script**: Paste your ad script, up to 1,500 characters, or draft one with the AI writer in a workflow. 2. **Pick a voice**: Choose a library voice, set the language and the delivery, and add emotion cues where you want them. 3. **See the cost**: The studio prices the voiceover by the characters in your script and shows the credits before anything runs. 4. **Use the voiceover**: Download the audio, lay it over B-roll with Merge Layers, or send it to a talking actor: OmniHuman 1.5 takes under 60 seconds of audio, and MiniMax H3 Max Lip Sync takes 5 to under 14.8 seconds. ### Best for - Ads in many languages - Talking actor ads - Voiceover on B-roll and demos - Teams without a voice actor - Agents that script and voice ads ### RiffAds in numbers - **74**: voice languages, including English, Spanish, Hindi, Arabic and Japanese. - **8**: credits for a script of about 30 seconds, billed by the character. 1 credit is $0.01. ### The numbers behind it - **25%+**: of watch time, on average, came from views in a non-primary language for YouTube creators who uploaded multi-language audio tracks.

The RiffAds Terms let you use library voices and your outputs in paid ads and client work. Two limits apply. Only use a recording of your own voice, or of someone who gave you written consent. And never let the voice speak as a customer who does not exist or never used the product. The FTC's reviews and testimonials rule bans fake testimonials like that. ### Does a text to speech voiceover need an AI label in TikTok ads? Yes, for an ad built in TikTok Ads Manager. TikTok's ad policy counts audio that is completely AI-generated as content that needs a disclaimer, so turn on 'This ad contains AI-generated content' or add your own clear label, or the ad can be rejected or restricted. Spark Ads follow the Community Guidelines instead: generic text to speech that is not a recognizable voice needs no label there, but a realistic AI person on screen does. ### Can I use my own voice in a video ad? Yes, as a recording. Upload an MP3, WAV, OGG or WEBM file of you speaking, and a talking actor lip-syncs to it with no text to speech step, so no voiceover is charged. Speech to Speech can also re-voice that recording in a library voice and keep your timing. Only upload your own voice, or one whose speaker gave you written consent. ### Can I add emotion to text to speech? Yes. Add emotion cues such as excited, happy, serious, whisper, sad, laugh or a short pause where you want them in the script, and the voice reads them as directions, not words. Voiceovers come in 74 languages. If the script is in a different language from the voice, RiffAds translates the text before the voice reads it, and your emotion cues stay where you put them. ### What is the difference between text to speech and a voice changer? Text to speech starts from words: you type a script and get new speech. A voice changer starts from a recording: it keeps the timing and delivery of the performance and swaps the voice. RiffAds has both. Text to Speech makes a voiceover from a script, Speech to Speech re-voices an audio file, and Change Voice re-voices the speech inside a video. ### How much does an AI voiceover cost? A voiceover is billed by the characters in the script, and the studio shows the credits before you generate. A script of about 30 seconds costs about 8 credits. A full 30 second talking actor ad, voice included, is about 848 credits. 1 credit is $0.01, credits never expire, and plans start at $49 a month. ### Can my AI agent make voiceovers for my ads? Yes. Through the API, MCP, Agent Skills and CLI, an agent such as Claude can list voices, get a free price quote and make a voiceover from the same credit balance as the studio. Its spending is capped by limits a person sets, which start at 600 credits per job and 2,000 per day. ## About RiffAds RiffAds makes realistic UGC video ads with AI actors, lip-synced to your script, in the studio or from your AI agent through API, MCP, Agent Skills and CLI.
