public sealed class SynthesisInput : IMessage<SynthesisInput>, IEquatable<SynthesisInput>, IDeepCloneable<SynthesisInput>, IBufferMessage, IMessage
Contains text input to be synthesized. Either text or ssml must be
supplied. Supplying both or neither returns
[google.rpc.Code.INVALID_ARGUMENT][]. The input size is limited to 5000
characters.
The SSML document to be synthesized. The SSML document must be valid
