Created a speech synthesis system based on the Animal Crossing series using Wwise and Unreal Engine 4.

Phonetic Events
To mirror the sound of the game, I recorded multiple variations of spoken phonemes, a few takes for each letter. These variations are then placed into random containers, where they are rapidly triggered by a character-specific events. By gently randomizing the delay time, the volume, and the pitch of each event, the impression of speech is created.

Punctuation
Depending on the punctuation mark at the end of a sentence, the events will be processed in different ways. Periods play the cues back in their default state, while exclamation points are given additional volume and a wider degree of pitch variation. Commas and spaces have longer delay times in order to create naturalistic pauses in the speech pattern.

Up-Speech
In order to capture the vocal phenomenon of up-speech, I needed to understand the length of the entire sentence. Once I had this variable, I was able to use an RTPC to track the percentage of the sentence that had already been spoken. This allows me to sculpt the tone and timbre of the performance from start to finish based on the punctuation mark used.

Implementation Breakdowns
I’m Ashton, a sound designer for video games and other forms of interactive media. Originally from Denver, Colorado, I’m based out of Los Angeles, California. Regardless of whether I’m creating assets or implementing them, I’m always seeking new chances to explore the intersection of design and integration.Currently, I work as a Senior Sound Designer at Respawn Entertainment, helping to design and implement sound effects for games within the Star Wars universe. Prior to this, I worked with Santa Monica Studio as a Technical Sound Designer, implementing sound effects on God of War: Ragnarök.When I’m not finding ways to enhance experiences through sound, you’ll find me failing to rank up in Street Fighter or meticulously planning my next tabletop role-playing game session.If you’d like to get in touch, feel free to shoot me an email at [email protected].
